+ <h2><a name="abstract" id="abstract"></a>Abstract</h2>
+ <p>This document specifies the distribution format exchange profile (DFXP) of the
+ timed text authoring format (TT AF) in terms of a vocabulary and semantics
+ thereof.</p>
+ <p>The timed text authoring format is a content type that represents timed text
+ media for the purpose of interchange among authoring systems. Timed text is textual
+ information that is intrinsically or extrinsically associated with timing
+ information.</p>
+ <p>The Distribution Format Exchange Profile is intended to be used for the purpose
+ of transcoding or exchanging timed text information among legacy distribution
+ content formats presently in use for subtitling and captioning functions.</p>
+ <p>In addition to being used for interchange among legacy distribution content
+ formats, DFXP content may be used directly as a distribution format, for example,
+ providing a standard content format to reference from a <code><text></code>
+ or <code><textstream></code> media object element in a <a
+ href="#smil21">[SMIL 2.1]</a> document.</p>

+ <h2><a name="status" id="status"></a>Status of this Document</h2>
+ <p><em>This section describes the status of this document at the time of its
+ publication. Other documents may supersede this document. A list of current W3C
+ publications and the latest revision of this technical report can be found in the
+ <a href="http://www.w3.org/TR/">W3C technical reports index</a> at
+ http://www.w3.org/TR/.</em></p>
+ <p>This is the 10 November 2006 Candidate Recommendation of the Timed Text
+ (TT) Authoring Format 1.0 – Distribution Format Exchange Profile (DFXP). W3C
+ publishes a Candidate Recommendation to indicate that the document is believed to
+ be stable and to encourage implementation by the developer community. The <a
+ href="http://www.w3.org/AudioVideo/TT/">Timed Text (TT) Working Group</a> expects
+ to request that the Director advance this document to Proposed Recommendation once
+ the Working Group has, for each test in the <a
+ href="http://www.w3.org/2006/DFXP/testsuite/Overview.html">DFXP
+ 1.0 Test Suite</a>,
+ demonstrated support by two interoperable implementations. The Working
+ Group, working closely with the developer community, expects to show these
+ implementations by 01 March 2007. This estimate is based in part on the preliminary
+ <a href="http://www.w3.org/2006/DFXP/DFXP-implementation-result.html">DFXP
+ Interoperability Implementation Report</a>. The Working Group does not plan to
+ request to advance to Proposed Recommendation prior to 01 April 2007.</p>
+ <p>This is a W3C Candidate Recommendation. The second Last Call Working Draft for
+ this specification resulted in a number of Last Call comments which have all been
+ addressed by the working group; a list of all Last Call comments can be found in
+ the <a href="http://www.w3.org/2005/03/21/DFXP-2ND-LastCallResponses.html">Second
+ Last Call Comments List</a>. The list of changes made since the last public Working
+ Draft is available in <a href="#change-history-lc2-to-cr"><b>M.2 Changes from
+ Second Last Call Working Draft to Candidate Recommendation</b></a>.</p>
+ <p>During the first Last Call period of this specification, there were <a
+ href="http://lists.w3.org/Archives/Public/public-tt/2005Apr/0040.html">unsatisfied
+ comments</a> that the working group was unable to resolve in a manner that satisfied
+ the commenter(s). The status of these comments has not changed during the second
+ Last Call period, as the working group continues to stand by its <a
+ href="http://lists.w3.org/Archives/Public/public-tt/2005Oct/0000.html">original
+ responses</a>. See also the <a
+ href="http://www.w3.org/2005/03/21/DFXPLastCallResponses.html#Issue11">First
+ Last Call Disposition of Comments</a> for a complete discussion.</p>
+ <p>The <em>dynamic flow processing</em> feature, as specified by the <a
+ href="#style-attribute-dynamicFlow"><code>tts:dynamicFlow</code></a> styling
+ attribute vocabulary, see also <a href="#dynamicFlowModel"><b>B Dynamic Flow
+ Processing Model</b></a>, has been determined to be <a
+ href="http://www.w3.org/2005/10/Process-20051014/tr.html#at-risk-feature">at
+ risk</a>, and is expected to be given the greatest scrutiny in the implementation

+ <p>The Timed Text Authoring Format (TT AF) Distribution Format Exchange Profile
+ (DFXP) provides a standardized representation of a particular subset of textual
+ information with which stylistic, layout, and timing semantics are associated by
+ an author or an authoring system for the purpose of interchange and potential
+ presentation.</p>
+ <p>DFXP is expressly designed to meet only a limited set of requirements
+ established by <a href="#ttaf1-req">[TTAF1-REQ]</a>, and summarized in <a
+ href="#requirements"><b>H Requirements</b></a>. In particular, only those
+ requirements which service the need of performing interchange with existing,
+ legacy distribution systems are satisfied.</p>
+ <p>In addition to being used for interchange among legacy distribution content
+ formats, DFXP content may be used directly as a distribution format, providing,
+ for example, a standard content format to reference from a
+ <code><text></code> or <code><textstream></code> media object element
+ in a <a href="#smil21">[SMIL 2.1]</a> document. Certain properties of DFXP
+ support streamability of content, as described in <a href="#streaming"><b>K
+ Streaming DFXP Content</b></a>.</p>
+ <div class="note">
+ <p class="prefix"><b>Note:</b></p>
+ <p>While DFXP was not expressly designed for direct (embedded) integration into
+ a SMIL document instance, such integration is not precluded.</p>
+ </div>
+ <div class="note">
+ <p class="prefix"><b>Note:</b></p>
+ <p>In some contexts of use, it may be appropriate to employ animated content to
+ depict sign language representations of the same content as expressed by a
+ Timed Text document instance. This use case is not explicitly addressed by DFXP
+ mechanisms, but may be addressed by some external multimedia integration
+ technology, such as SMIL.</p>

+ <div class="div2">
+ <h3><a name="model" id="model"></a>1.1 System Model</h3>
+ <p>Use of DFXP is intended to function in a wider context of Timed Text
+ Authoring and Distribution mechanisms that are based upon a system model,
+ depicted in <a href="#model-graphic"><b>Figure 1 – System Model</b></a>,
+ wherein the timed text authoring format serves as a bidirectional interchange
+ format among a heterogeneous collection of authoring systems, and as a
+ unidirectional interchange format to a heterogeneous collection of distribution
+ formats after undergoing transcoding or compilation to the target distribution
+ formats as required, and where one particular distribution format is DFXP.</p>

+ <p>Dynamic flow can be specified independently for flowing content into its

+ three phases of dynamic flow are specified using the <code>in()</code>,
+ <code>within()</code>, and <code>out()</code> flow functions
+ respectively.</p>
+ <p>Dynamic flow occurs on the basis of specific visual or semantic content
+ units. In the case of <code>pixel</code>, <code>glyph</code>,
+ <code>inline</code>, <code>line</code>, and <code>block</code>, the unit of
+ dynamic flow is based upon a visually rendered construct (<code>pixel</code>
+ or <code>glyph</code>) or upon an area of the area tree produced by
+ formatting the affected content. In the case of <code>character</code> and
+ <code>word</code>, the unit of dynamic flow is based upon a semantic unit
+ associated with one or more visually rendered or area units.</p>
+ <p>The dynamic flow unit <code>word</code> must be interpreted as being
+ dependent upon the language or writing system of the affected content. If the
+ language or writing system is unknown or unspecified, then <code>word</code>
+ is interpreted as follows:</p>
+ <ol type="1">
+ <li>
+ <p>If the affected content consists solely or mostly of Unified CJK
+ Ideographic characters or of characters of another Unicode character
+ block that are afforded similar treatment to that of Unified CJK
+ Ideographic characters, then <code>word</code> is to be interpreted as if
+ <code>character</code> were specified.</p>
+ </li>
+ <li>
+ <p>Otherwise, <code>word</code> is to be interpreted as denoting a
+ sequence of one or more characters that are not interpreted as an XML
+ whitespace character.</p>
+ </li>
+ </ol>
+ <p>When a flow unit is flowed into, within, or out of its region, the manner
+ by which the unit is flowed is controlled by the optional
+ <code>flowStyle</code> argument of the relevant flow function. If the flow
+ style is specified as <code>jump</code>, or if no flow style is specified,
+ then the flow unit is instantaneously transitioned into, within, or out of
+ the region. If the flow style is <code>smooth</code>, then the flow unit is
+ smoothly transitioned by means of pixel based exposure, movement, or hiding,
+ respectively. If the flow style is <code>fade</code>, then the flow unit is
+ faded into or out of the region by continuously incrementing or decrementing
+ the alpha component of the affected content.</p>
+ <p>In addition to the primary flow style, an optional flow transition effect
+ and flow transition effect style may be specified, in which case the

+ <div class="div2">
+ <h3><a name="dynamicFlowIntroduction" id="dynamicFlowIntroduction"></a>B.1
+ Introduction</h3>
+ <p><em>This sub-section is non-normative.</em></p>
+ <p>Dynamic flow provides a mechanism by means of which content may be flowed
+ through a presentation region over time where the rate of presentation is
+ dynamically determined by a presentation processor based upon the region's
+ extent, the textual content to be presented in the region, the formatting
+ styles applied to this content, and a set of parameters that control in-flow
+ and out-flow rates of content.</p>
+ <p>It is expected that this mechanism will be used by authors in a variety of
+ circumstances in order to specify behavior that would otherwise be impossible
+ or impractical to pre-compute at authoring time, since, for example, a region's
+ absolute size or the font metrics used to present content may not be known at
+ authoring time. In certain real-time streaming contexts, even the content is
+ not known at authoring time, but is only known at time of streaming.</p>
+ <p>In describing dynamic flow, the flow process is logically divided into three
+ types of flow operations:</p>
+ <ul>
+ <li>
+ <p><em>fill into</em> – causes new content to consume extent in the
+ designated presentation region;</p>
+ </li>
+ <li>
+ <p><em>reflow within</em> – causes content presently consuming extent
+ to be moved, possibly entailing new line break positions, within its
+ designated presentation region;</p>
+ </li>
+ <li>
+ <p><em>clear out</em> – causes content presently consuming extent in
+ the designated presentation region to no longer consume extent.</p>
+ </li>
+ </ul>
+ <p>Each region subject to dynamic flow processing may be modeled in terms
+ of:</p>
+ <ol type="1">
+ <li>
+ <p>the region with a definite extent, into which content is to be
+ flowed;</p>
+ </li>
+ <li>
+ <p>a content buffer consisting of a sequence of content blocks, each of
+ which consists of a sequence of content inlines (spans), where each block
+ and inline has a computed style set, and where an inline has a (possibly
+ empty) sequence of characters that express the textual content of the
+ inline;</p>
+ </li>
+ <li>
+ <p>two independent flow operation single-shot timers: a fill timer and a
+ clear timer;</p>
+ </li>
+ <li>
+ <p>a set of state parameters that includes:</p>
+ <ol type="a">

+ <p>The encoding of a TT AF document must be determined by the XML encoding
+ declaration. This has identical semantics to the application/xml media type
+ in the case where the charset parameter is omitted, as specified in <a
+ href="#xml-media">[XML Media]</a>, Sections 8.9, 8.10 and 8.11.</p>
+ <p>The document profile of a TT AF document may be specified using an
+ optional <code>profile</code> parameter, which, if specified, the value of
+ which must adhere to the syntax and semantics of <code>ttp:profile</code>
+ parameter defined by Section <a href="#parameter-attribute-profile"><b>6.2.7

+ <dt class="label">Security considerations:</dt>
+ <dd>
+ <p>As with other XML types and as noted in <a href="#xml-media">[XML
+ Media]</a> Section 10, repeated expansion of maliciously constructed XML
+ entities can be used to consume large amounts of memory, which may cause XML
+ processors in constrained environments to fail.</p>
+ <p>In addition, because of the extensibility features for TT AF and of XML in
+ general, it is possible that "application/ttaf+xml" may describe content that
+ has security implications beyond those described here. However, if the
+ processor follows only the normative semantics of the published
+ specification, this content will be outside TT AF namespaces and may be
+ ignored. Only in the case where the processor recognizes and processes the
+ additional content, or where further processing of that content is dispatched
+ to other processors, would security issues potentially arise. And in that
+ case, they would fall outside the domain of this registration document.</p>
+ </dd>
+ <dt class="label">Interoperability considerations:</dt>
+ <dd>
+ <p>The published specification describes processing semantics that dictate
+ behavior that must be followed when dealing with, among other things,
+ unrecognized elements and attributes, both in TT AF namespaces and in other
+ namespaces.</p>
+ <p>Because TT AF is extensible, conformant "application/ttaf+xml" processors
+ must expect that content received is well-formed XML, but it cannot be
+ guaranteed that the content is valid to a particular DTD or Schema or that
+ the processor will recognize all of the elements and attributes in the
+ document.</p>

+ <p>The first column of <a href="#attribute-vocab-derivation-table"><b>Table I-2
+ – Attributes</b></a> specifies a TT AF attribute vocabulary item; the second
+ column specifies the syntactic and/or semantic model on which the vocabulary
+ item is based; the third column specifies the reference that defines the model
+ (if a model is indicated); the fourth column specifies details about the
+ derivation; the last column refers to additional notes describing the nature of
+ the derivation.</p>
+ <p>In the fourth column, which describes details of derivation, a notation is
+ use to indicate the addition or removal of an attribute value. For example, in
+ the derivation of the <code>timeContainer</code> attribute, the details column
+ includes "-excl", which denotes that the <code>excl</code> value that is
+ specified for use with the <code>timeContainer</code> model attribute is not
+ specified for use with the corresponding TT AF attribute; similarly, an
+ "+<em>value</em>" in the details column indicates that the attribute's values
+ have been extended to include <em>value</em>.</p>
+ <p>Only those attributes that are specified for use on more than one TT AF
+ element type are listed below. Those per-element namespace attributes that are
+ uniquely defined for a specific TT AF element type are not listed below, but
+ are considered to be part of the specific element type's derivation described

+ <h2><a name="streaming" id="streaming"></a>K Streaming DFXP Content
+ (Non-Normative)</h2>
+ <p>DFXP Content is designed to support streamability by implementing the
+ following properties:</p>
+ <ul>
+ <li>
+ <p>can be progressively encoded (i.e., does not require computing subsequent
+ data prior to sending current data);</p>
+ </li>
+ <li>
+ <p>can be progressively decoded (i.e., does not require forward references,
+ but uses only reverse references when necessary);</p>
+ </li>
+ <li>
+ <p>does not require dereferencing (and subsequent loading) of any resources
+ other than DFXP content (i.e., no embedded URIs);</p>
+ </li>
+ <li>
+ <p>does not support alternative content forms (e.g., different language,
+ graphics formats, time bases) in a single document;</p>
+ </li>
+ <li>
+ <p>has timing structure compiled into inline format that makes possible a
+ temporal ordering of content that follows temporal presentation order;</p>
+ </li>
+ <li>
+ <p>constrains content models to prevent arbitrary nested content
+ structures;</p>
+ </li>
+ </ul>
+ <p>One possible means by which DFXP Content may be streamed is to partition a
+ DFXP document instance's information set into non-overlapping fragments, where
+ one particular fragment, call it the <em>root fragment</em>, represents the front
+ matter (head) of the document instance as well as its top level structural
+ elements, and other fragments represent content whose time intervals are expected
+ to be active in parallel.</p>
+ <p>In applications that require arbitrary (random) entry into a stream, i.e., the
+ property of being able to start reading data at an arbitrary data access unit,
+ the root fragment will be repetitively transmitted (inserted) into the stream in
+ order to permit a decoder to resynchronize and acquire sufficient structural
+ information in the information set in order to interpret subsequent content
+ fragments.</p>
+ <p>An example of such a fragmentation of a DFXP document instance is shown in <a
+ href="#fragment-streaming-graphic"><b>Figure 2 – Fragment Streaming</b></a>.</p>

+ Changes from First to Second Last Call Working Draft</h3>
+ <div class="exampleInner">
+<pre>
+<span class="strong">Technical Changes</span>
+
+The following changes result in a technical change of the conformance
+criteria, the normative abstract document type that is defined
+for use with DFXP, or the defined value space of an attribute or
+property:
+
+* Update namespace URIs to use 2006/04 instead of 2004/11;
+* Remove ttp:defaultLengthUnit definition and all references;
+ + change initial (default) value definition of tts:fontSize to
+ be 1/24th of the height of the root container in all cases;
+ + change syntax of scalar form of <length> to require units
+* Remove ttp:defaultTimeMetric definition and all references;
+ + change syntax of <duration> to require a metric
+* Add "transcription" to ttm:role enumeration in section 12.2.2;
+* In section 8.2.16, change "dynamic" value to read "scroll" instead,
+ which is already defined by CSS/XSL and given UA dependent
+ semantics; here we will specify fixed semantics and map to dynamic
+ flow; change also usage in 8.1.7 to refer to "scroll";
+* In section 6.2.1, change implied default value of ttp:cellResolution
+ from 1col/1row to 32cols/15rows, based on CEA/EIA-608-C maximum values;
+* In 8.3.12, add "cyan" and "magenta" as aliases for "aqua" and
+ "fucshia", since it turns out these are defined by SVG1.0;
+* Add following new values for ttm:role to support EIA/CEA-708 caption
+ text functions: dialog, expletive, narration, quality, source,
+ suppressed; remove associated editorial note;
+* In 3.1, add new conformance criteria item 1 that specifies the use
+ of application/ttaf+xml as MIME media type with optional "profile"
+ parameter; use new references to MIME and XML Media Types;
+* Remove begin, dur, and end attributes and descriptions thereof from
+ <tt/> and <layout/>;
+* Move description of tts:extent attribute from <tt/> to
+ <body/>;
+* Change "meta" element name to "metadata" to match SVG usage, on
+ which this vocabulary item is modeled;
+* Remove name attribute from <metadata/> element;
+* Change initial (default) value definition of tts:fontSize to
+ be 1c (one grid cell) in order to match implied default value for
+ ttp:cellResolution row count;
+* For sake of symmetry, add Metadata.class and Animation.class children to
+ content model of <br/>;
+* Add style, ttm:*, tts:* and foreign namespace attributes to
+ <br/>;
+* Add usage of tts:padding property that takes three length specifications;
+* Add left and right values to textAlign;
+* Add monospace, serif, and sansSerif to generic font family names;
+* Add missing "auto" value to zIndex, and make "auto" initial value
+ in order to comply with XSL/CSS usage;
+* Add means to specify rate (in units per second) to definition of
+ flowIntervalArguments in section 8.3.8;
+* Populate Appendix B on Dynamic Flow Processing which defines normative
+ semantics (previously unspecified);
+
+<span class="strong">Editorial Changes</span>
+
+The following changes are editorial in nature or entail semantic
+clarifications that do not affect the abstract document type or defined
+schemas for DFXP:
+
+* Add "Contributing Authors" to preamble, listing contributors;
+* Merge current and former members description in Appendix H (now
+ Appendix K);
+* Remove references to AFXP as follows:
+ + remove 1st note in section 1
+ + remove 1st note in section 1.1
+ + remove definition of AFXP from glossary
+ + remove section 4.2
+ + remove AFXP profile entry from Table 2 - Profiles
+ + remove reference to 2nd catalog in section 5.3 preamble
+ + remove last clause of 2nd para of section 5.3
+ + change "AFXP" to "future profiles" in 1st para of section 5.3.1
+ + remove section 5.3.2
+ + remove last sentence of 2nd note in section 7.1.4
+ + remove last sentence of 1st note in section 7.1.6
+ + change "AFXP" to "advanced profiles" in 3rd para of Appendix H (now
+ Appendix K);
+* Add clarifying language in the last para of section 8.3.6;
+* Clarify definition of "Valid Abstract Document Instance" in section 4
+ to account for the pruning of attributes in other namespaces and
+ residual requirements on the presence and value type of attributes;
+ + remove redundant definition in glossary to prevent competing
+ definitions
+* Add informative reference to SMPTE170M (for NTSC); add a
+ reference to this bibliographic entry from the 1st note under
+ section 6.2.4; add new sentence to this same note indicating
+ that other frame rate multipliers apply in other regions and
+ with other video formats;
+* Add normative reference to UAAG; add recommendation in
+ conformance clause 3.2 item (5) that a presentation processor
+ should satisfy UAAG defined guidelines;
+* Add note in introduction expressing that a related sign language
+ representation may be appropriate in some circumstances, but that
+ this is not addressed explicitly by DFXP;
+* Add note in section 6.2.11 indicating that control over state of
+ external media time base is outside the scope of DFXP;
+* Add note in section 5.2 indicating possible uses of profile
+ information;
+* Fix typos:
+ + section 6.2.1: s/express number/express the number/
+ + section 6.2.5 (now 6.2.3): s/in document/in a document/
+ + section 6.2.6 (now 6.2.4): s/MHz/Hz/
+* Add note to 6.2.2 referring to section 10.3 Time Value Expressions;

+* Add normative reference to GPS, using reference in section 6.2.2;
+* Add note to 6.2.2 summarizing difference between GPS and UTC;
+* Add para to 6.2.2 clarifying that ttp:clockMode is significant
+ only on <tt/> element;
+* In section 8.3.11, add or refer to definitions of "px", "em", and
+ "c";
+* In section 7.2.3, replace definition of semantics of xml:space
+ values with a new definition that maps to XSL-FO properties;
+* In section 9.3.2, add new item (8) that specifies mapping for
+ <br/> elements to <fo:character/>;
+* In section 4, add new step 2 to definition of Abstract Document
+ Instance, which is needed to remove certain XML whitespace that
+ remains after pruning elements; e.g., a <br/> element may have
+ children from another namespace, that, after pruning, would result
+ in a non-empty <br/> element; this new step ensures that the
+ element is emptied prior to validation against its abstract
+ document type;
+* In section 8 preamble, add new para indicating that no normative
+ use of a stylesheet PI is defined;
+* In section 8.2.16, add condition tts:wrapOption="noWrap" in note;
+* In section 8.2.22, move visibility="hidden" from <p/> to <span/>s;
+ otherwise, content would remain hidden due to <p/> being hidden;
+* Add informative reference to CEA/EIA-608-C; use this reference
+ in a new note in 6.2.1;
+* Add note in 6.2.1 explaining that it is not expected that glyph
+ areas align with uniform grid defined by ttp:cellResolution,
+ indicate that such alignment would occur only when using monospace
+ font whose EM square exactly matches grid's cell size;
+* Add normative reference to SRGB definition;
+* Add normative use of SRGB in section 8.3.2 <color> and 8.3.12 <namedColor>
+* In 8.3.2, add para indicating that SRGB is used for both input and
+ output of notional composition functions; add note indicating that
+ a presentation processor may actually use another color space for
+ internal or external purposes;
+* In 8.2.14, specify that opacity applies on a linear scale;
+* Add informative reference to SVG 1.0;
+* Add note in 8.3.12 indicating that named color set is a strict
+ subset of SVG 1.0 named color set;
+* Add empty informative Appendices H, I, and L, to document Vocabulary
+ Derivation, QA Framework Compliance, and Change History,
+ respectively; renumber former appendices G and H as Appendices J
+ and K, respectively;
+* Add normative reference to RFC2046, MIME Media Types;
+* Add normative reference to RFC3023, XML Media Types;
+* Change description of implied begin/end on <tt/> to refer to
+ external context temporal interval;
+* Change description of implied begin/end on <body/> to refer to
+ external time interval;
+* In 7.1.2, 8.1.1, and 9.1.1, specify that implied time intervals of
+ head, styling, and layout are coterminous with external time
+ interval;
+* In 9.1.2, indicate that begin/end points specified on <region/>
+ are relative to the time interval of the nearest ancestor associated
+ with a time interval;
+* In 9.1.2, remove constraint that if no tts:extent is specified in
+ computed style set then no content is flowed into region; this
+ constraint is redundant since the initial value of tts:extent is
+ "auto" which is defined to be extent of root container;
+* Fix typos:
+ + section 9.1.2, s/layout/region/ in para describing dur attribute;
+* Add note at end of the preamble to section 8.2, [Styling] Attribute
+ Vocabulary, indicating that (to support inheritance) any style
+ property may be specified on any content element independently of
+ whether it applies to that element;
+* Remove note in 7.1.7 that indicated that <br/> is empty in
+ the reduced XML infoset, which no longer holds as both metadata and
+ animation children may be present;
+* In Appendix I, add table I-1 with element vocabulary derivation;
+* Define monospace to be either serifed or not; define serif and
+ sansSerif to be equivalent to proportionalSerif and proportionalSansSerif,
+ respectively;
+* Add time metric to time expressions in example content;
+* Add definition of implicit duration of document instance in section 7.1.1;
+* In definition of <time-expression> syntax in section 10.3.1,
+ remove paragraph referring to default time metric, which no longer
+ applies now that time metric must be specified;
+* In Appendix I, add table I-2 with attribute vocabulary derivation;
+* Add definition of percentage lengths to each style property
+ definition. Percentages apply to the following styles: extent,
+ fontSize, lineHeight, origin, padding, and textOutline;
+* Fill in Appendix I with QA Framework compliance information;
+* Add section 5.3.2 defining a presently empty "Extension Catalog"
+ that serves as a placeholder for future standardized extensions and
+ additionally specifies that document instance may contain arbitrary
+ namespace qualified elements and attributes from other namespaces;
+* Add section 3.3 defining conformance claims and requirements
+ regarding for providing an implementation compliance statement;
+* Add hyperlinks throughout document for references to elements,
+ attributes, and value expressions;
+* Add new Appendix F containing sample code and sample compile,
+ load, run session transcript;
+* Change IDREF to IDREFS as value of ttm:agent as found in prose in
+ section 12.2.1;

+
+<span class="strong">Editorial Changes</span>
+
+The following changes are editorial in nature or entail semantic

+
+* Update "status of this document" (SOTD) section to
+ reflect CR transition.
+* Add normative reference to xml:id recommendation.
+* Add note in section 9.3.3 indicating that intermediate document

+ sequences (which might have been confusing).
+* Revise content models of XML Representation of div, p,
+ and span element information items in order to make
+ reference to Block.class and Inline.class element

+* Add clarifications in sections 8.3.13 and 8.3.14 that
+ syntactic element "char" adheres to production [2] of
+ XML1.1, while syntactic element "S" adheres to
+ production [3] of XML1.1.
+* Add note to section 7.1.7 (and rearrange paragraph ordering)

+<p><emph>Unless specified otherwise, this section and its sub-sections are non-normative.</emph></p>
+<p>The Timed Text Authoring Format (TT AF) Distribution Format Exchange Profile (DFXP)
+provides a standardized representation of a particular subset of
+textual information with which stylistic, layout, and timing semantics are associated by
+an author or an authoring system for the purpose of interchange and potential presentation.</p>
+<p>DFXP is expressly designed to meet only a limited set of requirements
+established by <bibref ref="ttaf1-req"/>, and summarized in <specref
+ref="requirements"/>. In particular, only those requirements which service the
+need of performing interchange with existing, legacy distribution systems are
+satisfied.</p>
+<p>In addition to being used for interchange among legacy distribution content
+formats, DFXP content may be used directly as a distribution format, providing, for
+example, a standard content format to reference from a <el><text></el> or
+<el><textstream></el> media object element in a <bibref
+ref="smil21"/> document. Certain properties of DFXP support
+streamability of content, as described in <specref ref="streaming"/>.</p>
+<note>
+<p>While DFXP was not expressly designed for direct (embedded) integration into a
+SMIL document instance, such integration is not precluded.</p>
+</note>
+<note>
+<p>In some contexts of use, it may be appropriate to employ
+animated content to depict sign language representations of the same content
+as expressed by a Timed Text document instance. This use case is not
+explicitly addressed by DFXP mechanisms, but may be addressed by some
+external multimedia integration technology, such as SMIL.</p>
+</note>
+<div2 id="model">
+<head>System Model</head>
+<p>Use of DFXP is intended to function in a wider context of Timed Text
+Authoring and Distribution mechanisms that are based upon a system
+model, depicted in <specref ref="model-graphic"/>, wherein the timed text authoring format
+serves as a bidirectional interchange format among a heterogeneous collection of
+authoring systems, and as a unidirectional interchange format to a
+heterogeneous collection of distribution formats after undergoing transcoding
+or compilation to the target distribution formats as required, and where one
+particular distribution format is DFXP.</p>

+The hierarchical organization of content elements serves a primary role in

+<specref ref="dfxp-example-body"/>, each paragraph (<el>p</el> element)
+is flowed into its target region in the specified lexical order; furthermore,
+the active time interval of each paragraph is timed in accordance to its
+parent or sibling according to the applicable time containment semantics —
+in this case, the division parent is interpreted as a parallel time
+container.</p>

+the nearest ancestor that specifies a region determines the
+region. Note also that content is presented

+<p>The semantics of the value <code>default</code> are fixed to mean that
+white space that appears in element content as defined by <bibref
+ref="xml11"/>, §3.2.1, must be normalized at the
+application layer during subsequent processing, such as presentation or
+transformation processing, as follows:</p>
+<olist>
+<item><p>replace each TAB character (<code>&#x0009;</code>) and NEWLINE character (<code>&#x000A;</code>) with a SPACE
+character (<code>&#x0020;</code>);</p></item>
+<item><p>replace each sequence of two or more SPACE characters with a
+single SPACE character;</p></item>
+<item><p>for every maximum sequence of sibling character information
+items, if there is a leading or trailing SPACE character in the
+sequence, then remove the character.</p></item>
+</olist>
+-->
+<!-- NEW DEFINITION -->
+<p>The semantics of the value <code>default</code> are fixed to mean that
+when performing presentation processing of a document instance as
+described by <specref ref="semantics-region-layout-step-2"/>,
+processing must occur as
+if the following properties were specified on the affected
+elements of the intermediate XSL-FO document:</p>
+<ulist>
+<item>
+<p><code>suppress-at-line-break="auto"</code></p>
+</item>
+<item>
+<p><code>linefeed-treatment="treat-as-space"</code></p>
+</item>
+<item>
+<p><code>white-space-collapse="true"</code></p>
+</item>
+<item>
+<p><code>white-space-treatment="ignore-if-surrounding-linefeed"</code></p>
+</item>
+</ulist>
+<p>Similarly, the semantics of the value <code>preserve</code> are fixed to mean that
+when performing presentation processing, processing must occur as
+if the following properties were specified on the affected
+elements of the intermediate XSL-FO document:</p>
+<ulist>
+<item>
+<p><code>suppress-at-line-break="retain"</code></p>
+</item>
+<item>
+<p><code>linefeed-treatment="preserve"</code></p>

+<p><code>white-space-collapse="false"</code></p>
+</item>
+<item>
+<p><code>white-space-treatment="preserve"</code></p>
+</item>
+</ulist>
+<p>When performing other types of processing intended to eventually
+result in a visual presentation by means other than those described
+in this specification, the semantics of space collapsing and
+preservation as described above should be respected. For other types
+of processing, the treatment of the <att>xml:space</att> attribute
+is processor dependent, but should respect the semantics described
+above if possible.</p>

+<p>Dynamic flow can be specified independently for flowing content
+into its region, flowing it within its region, and flowing it out of
+its region. These three phases of dynamic flow are specified using the
+<code>in()</code>, <code>within()</code>, and <code>out()</code> flow
+functions respectively.</p>
+<p>Dynamic flow occurs on the basis of specific visual or semantic
+content units. In the case of <code>pixel</code>, <code>glyph</code>,
+<code>inline</code>, <code>line</code>, and <code>block</code>, the
+unit of dynamic flow is based upon a visually rendered construct
+(<code>pixel</code> or <code>glyph</code>) or upon an area of the area
+tree produced by formatting the affected content. In the case of
+<code>character</code> and <code>word</code>, the unit of dynamic flow
+is based upon a semantic unit associated with one or more visually
+rendered or area units.</p>
+<p>The dynamic flow unit <code>word</code> must be interpreted as
+being dependent upon the language or writing system of the affected
+content. If the language or writing system is unknown or unspecified,
+then <code>word</code> is interpreted as follows:</p>
+<olist>
+<item><p>If the affected content consists solely or mostly of Unified CJK
+Ideographic characters or of characters of another Unicode character
+block that are afforded similar treatment to that of Unified CJK
+Ideographic characters, then <code>word</code> is to be interpreted
+as if <code>character</code> were specified.</p></item>
+<item><p>Otherwise, <code>word</code> is to be interpreted as denoting
+a sequence of one or more characters that are not interpreted as an
+XML whitespace character.</p></item>
+</olist>
+<p>When a flow unit is flowed into, within, or out of its region, the
+manner by which the unit is flowed is controlled by the optional
+<code>flowStyle</code> argument of the relevant flow function. If the
+flow style is specified as <code>jump</code>, or if no flow style is
+specified, then the flow unit is instantaneously transitioned into,
+within, or out of the region. If the flow style is
+<code>smooth</code>, then the flow unit is smoothly transitioned by
+means of pixel based exposure, movement, or hiding, respectively. If
+the flow style is <code>fade</code>, then the flow unit is faded into
+or out of the region by continuously incrementing or decrementing the
+alpha component of the affected content.</p>
+<p>In addition to the primary flow style, an optional flow transition
+effect and flow transition effect style may be specified, in which
+case the transition effect is additively (and simultaneously) applied
+to the primary flow style transition.</p>
+<p>For the permitted values of <code>flowTransition</code> and

+<head>Introduction</head>
+<p><emph>This sub-section is non-normative.</emph></p>
+<p>Dynamic flow provides a mechanism by means of which content may be
+flowed through a presentation region over time where the rate of
+presentation is dynamically determined by a presentation processor
+based upon the region's extent, the textual content to be presented in
+the region, the formatting styles applied to this content, and a set
+of parameters that control in-flow and out-flow rates of content.</p>
+<p>It is expected that this mechanism will be used by authors in a
+variety of circumstances in order to specify behavior that would
+otherwise be impossible or impractical to pre-compute at authoring time, since, for
+example, a region's absolute size or the font metrics used to present
+content may not be known at authoring time. In certain real-time
+streaming contexts, even the content is not known at authoring time,
+but is only known at time of streaming.</p>
+<p>In describing dynamic flow, the flow process is logically divided
+into three types of flow operations:</p>
+<ulist>
+<item><p><emph>fill into</emph> – causes new content
+to consume extent in the designated presentation region;</p></item>
+<item><p><emph>reflow within</emph> – causes content
+presently consuming extent to be moved, possibly entailing new line break
+positions, within its designated
+presentation region;</p></item>
+<item><p><emph>clear out</emph> – causes content
+presently consuming extent in the designated presentation region to no
+longer consume extent.</p></item>
+</ulist>
+<p>Each region subject to dynamic flow processing may be modeled in terms of:</p>
+<olist>
+<item><p>the region with a definite extent, into which content is to be
+flowed;</p></item>
+<item><p>a content buffer consisting of a sequence of content blocks,
+each of which consists of a sequence of content inlines (spans), where
+each block and inline has a computed style set, and where an inline
+has a (possibly empty) sequence of characters that express the textual
+content of the inline;</p></item>
+<item><p>two independent flow operation single-shot timers: a fill timer and a clear
+timer;</p></item>

+<p>The encoding of a TT AF document must be determined by the XML
+encoding declaration. This has identical semantics to the
+application/xml media type in the case where the charset parameter is
+omitted, as specified in <bibref ref="xml-media"/>, Sections 8.9,
+8.10 and 8.11.</p>
+<p>The document profile of a TT AF document may be specified using
+an optional <code>profile</code> parameter, which, if specified,
+the value of which must adhere to the syntax and semantics of
+<att>ttp:profile</att> parameter defined by
+Section
+<specref ref="parameter-attribute-profile"/>

+<label>Security considerations:</label>
+<def>
+<p>As with other XML types and as noted in
+<bibref ref="xml-media"/>
+Section 10, repeated expansion of maliciously constructed XML entities
+can be used to consume large amounts of memory, which may cause XML
+processors in constrained environments to fail.</p>
+<p>In addition, because of the extensibility features for TT AF and of XML
+in general, it is possible that "application/ttaf+xml" may describe content
+that has security implications beyond those described here. However,
+if the processor follows only the normative semantics of the published
+specification, this content will be outside TT AF namespaces and
+may be ignored. Only in the case where the processor recognizes and
+processes the additional content, or where further processing of that
+content is dispatched to other processors, would security issues
+potentially arise. And in that case, they would fall outside the
+domain of this registration document.</p>
+</def>
+</gitem>
+<gitem>
+<label>Interoperability considerations:</label>
+<def>
+<p>The published specification describes processing semantics that dictate
+behavior that must be followed when dealing with, among other things,
+unrecognized elements and attributes, both in TT AF namespaces and in
+other namespaces.</p>
+<p>Because TT AF is extensible, conformant "application/ttaf+xml" processors must
+expect that content received is well-formed XML, but it cannot be
+guaranteed that the content is valid to a particular DTD or Schema or
+that the processor will recognize all of the elements and attributes
+in the document.</p>

+vocabulary, separately describing derivation of elements and

+<div2>
+<head>Element Derivation</head>
+<p>The first column of <specref ref="element-vocab-derivation-table"/>
+specifies a TT AF element vocabulary item; the second column specifies the
+syntactic and/or semantic model on which the vocabulary item is based;
+the third column specifies the reference that defines
+the model (if a model is indicated);
+the fourth column specifies details about the derivation; the last
+column refers to additional notes describing the nature of the
+derivation.</p>
+<p>In the fourth column, which describes details of derivation, a
+notation is use to indicate the addition or removal of an attribute.
+For example, in the derivation of the <el>tt:div</el> element, the
+details column includes "-@class", which denotes that the
+<att>class</att> attribute that is specified for use with the
+<el>xhtml:div</el> model element is not specified for use with the
+corresponding TT AF element; in contrast, the details column includes
+"+@begin", which denotes that a <att>begin</att> attribute is added
+that is not specified for use with the <el>xhtml:div</el> model
+element.</p>

+<head>Streaming DFXP Content</head>
+<p>DFXP Content is designed to support streamability by implementing the

+<item>
+<p>can be progressively encoded (i.e., does not require computing
+subsequent data prior to sending current data);</p>
+</item>
+<item>
+<p>can be progressively decoded (i.e., does not require forward

+<p>does not require dereferencing (and subsequent loading) of any
+resources other than DFXP content (i.e., no embedded URIs);</p>

+<p>does not support alternative content forms (e.g., different
+language, graphics formats, time bases) in a single document;</p>
+</item>

+presentation order;</p>
+</item>
+<item>
+<p>constrains content models to prevent arbitrary nested content
+structures;</p>
+</item>
+</ulist>
+<p>One possible means by which DFXP Content may be streamed is to
+partition a DFXP document instance's information set into
+non-overlapping fragments, where one particular fragment, call it the
+<emph>root fragment</emph>, represents the front matter (head) of the
+document instance as well as its top level structural elements, and
+other fragments represent content whose time intervals are expected to
+be active in parallel.</p>
+<p>In applications that require arbitrary (random) entry into a
+stream, i.e., the property of being able to start reading data at an
+arbitrary data access unit, the root fragment will be repetitively
+transmitted (inserted) into the stream in order to permit a decoder to
+resynchronize and acquire sufficient structural information in the
+information set in order to interpret subsequent content
+fragments.</p>

+<head>Changes from First to Second Last Call Working Draft</head>
+<eg xml:space="preserve">
+<phrase role="strong">Technical Changes</phrase>
+
+The following changes result in a technical change of the conformance
+criteria, the normative abstract document type that is defined
+for use with DFXP, or the defined value space of an attribute or
+property:
+
+* Update namespace URIs to use 2006/04 instead of 2004/11;
+* Remove ttp:defaultLengthUnit definition and all references;
+ + change initial (default) value definition of tts:fontSize to
+ be 1/24th of the height of the root container in all cases;
+ + change syntax of scalar form of <length> to require units
+* Remove ttp:defaultTimeMetric definition and all references;
+ + change syntax of <duration> to require a metric
+* Add "transcription" to ttm:role enumeration in section 12.2.2;
+* In section 8.2.16, change "dynamic" value to read "scroll" instead,
+ which is already defined by CSS/XSL and given UA dependent
+ semantics; here we will specify fixed semantics and map to dynamic
+ flow; change also usage in 8.1.7 to refer to "scroll";
+* In section 6.2.1, change implied default value of ttp:cellResolution
+ from 1col/1row to 32cols/15rows, based on CEA/EIA-608-C maximum values;
+* In 8.3.12, add "cyan" and "magenta" as aliases for "aqua" and
+ "fucshia", since it turns out these are defined by SVG1.0;
+* Add following new values for ttm:role to support EIA/CEA-708 caption
+ text functions: dialog, expletive, narration, quality, source,
+ suppressed; remove associated editorial note;
+* In 3.1, add new conformance criteria item 1 that specifies the use
+ of application/ttaf+xml as MIME media type with optional "profile"
+ parameter; use new references to MIME and XML Media Types;
+* Remove begin, dur, and end attributes and descriptions thereof from
+ <tt/> and <layout/>;
+* Move description of tts:extent attribute from <tt/> to
+ <body/>;
+* Change "meta" element name to "metadata" to match SVG usage, on
+ which this vocabulary item is modeled;
+* Remove name attribute from <metadata/> element;
+* Change initial (default) value definition of tts:fontSize to
+ be 1c (one grid cell) in order to match implied default value for
+ ttp:cellResolution row count;
+* For sake of symmetry, add Metadata.class and Animation.class children to
+ content model of <br/>;
+* Add style, ttm:*, tts:* and foreign namespace attributes to
+ <br/>;
+* Add usage of tts:padding property that takes three length specifications;
+* Add left and right values to textAlign;
+* Add monospace, serif, and sansSerif to generic font family names;
+* Add missing "auto" value to zIndex, and make "auto" initial value
+ in order to comply with XSL/CSS usage;
+* Add means to specify rate (in units per second) to definition of
+ flowIntervalArguments in section 8.3.8;
+* Populate Appendix B on Dynamic Flow Processing which defines normative
+ semantics (previously unspecified);
+
+<phrase role="strong">Editorial Changes</phrase>
+
+The following changes are editorial in nature or entail semantic
+clarifications that do not affect the abstract document type or defined
+schemas for DFXP:
+
+* Add "Contributing Authors" to preamble, listing contributors;
+* Merge current and former members description in Appendix H (now
+ Appendix K);
+* Remove references to AFXP as follows:
+ + remove 1st note in section 1
+ + remove 1st note in section 1.1
+ + remove definition of AFXP from glossary
+ + remove section 4.2
+ + remove AFXP profile entry from Table 2 - Profiles
+ + remove reference to 2nd catalog in section 5.3 preamble
+ + remove last clause of 2nd para of section 5.3
+ + change "AFXP" to "future profiles" in 1st para of section 5.3.1
+ + remove section 5.3.2
+ + remove last sentence of 2nd note in section 7.1.4
+ + remove last sentence of 1st note in section 7.1.6
+ + change "AFXP" to "advanced profiles" in 3rd para of Appendix H (now
+ Appendix K);
+* Add clarifying language in the last para of section 8.3.6;
+* Clarify definition of "Valid Abstract Document Instance" in section 4
+ to account for the pruning of attributes in other namespaces and
+ residual requirements on the presence and value type of attributes;
+ + remove redundant definition in glossary to prevent competing
+ definitions
+* Add informative reference to SMPTE170M (for NTSC); add a
+ reference to this bibliographic entry from the 1st note under
+ section 6.2.4; add new sentence to this same note indicating
+ that other frame rate multipliers apply in other regions and
+ with other video formats;
+* Add normative reference to UAAG; add recommendation in
+ conformance clause 3.2 item (5) that a presentation processor
+ should satisfy UAAG defined guidelines;
+* Add note in introduction expressing that a related sign language
+ representation may be appropriate in some circumstances, but that
+ this is not addressed explicitly by DFXP;
+* Add note in section 6.2.11 indicating that control over state of
+ external media time base is outside the scope of DFXP;
+* Add note in section 5.2 indicating possible uses of profile
+ information;
+* Fix typos:
+ + section 6.2.1: s/express number/express the number/
+ + section 6.2.5 (now 6.2.3): s/in document/in a document/
+ + section 6.2.6 (now 6.2.4): s/MHz/Hz/
+* Add note to 6.2.2 referring to section 10.3 Time Value Expressions;
+* Add normative reference to UTC, using reference in section 6.2.2;
+* Add normative reference to GPS, using reference in section 6.2.2;
+* Add note to 6.2.2 summarizing difference between GPS and UTC;
+* Add para to 6.2.2 clarifying that ttp:clockMode is significant
+ only on <tt/> element;
+* In section 8.3.11, add or refer to definitions of "px", "em", and
+ "c";
+* In section 7.2.3, replace definition of semantics of xml:space
+ values with a new definition that maps to XSL-FO properties;
+* In section 9.3.2, add new item (8) that specifies mapping for
+ <br/> elements to <fo:character/>;
+* In section 4, add new step 2 to definition of Abstract Document
+ Instance, which is needed to remove certain XML whitespace that
+ remains after pruning elements; e.g., a <br/> element may have
+ children from another namespace, that, after pruning, would result
+ in a non-empty <br/> element; this new step ensures that the
+ element is emptied prior to validation against its abstract
+ document type;
+* In section 8 preamble, add new para indicating that no normative
+ use of a stylesheet PI is defined;
+* In section 8.2.16, add condition tts:wrapOption="noWrap" in note;
+* In section 8.2.22, move visibility="hidden" from <p/> to <span/>s;
+ otherwise, content would remain hidden due to <p/> being hidden;
+* Add informative reference to CEA/EIA-608-C; use this reference
+ in a new note in 6.2.1;

+ internal or external purposes;
+* In 8.2.14, specify that opacity applies on a linear scale;
+* Add informative reference to SVG 1.0;

+ Derivation, QA Framework Compliance, and Change History,
+ respectively; renumber former appendices G and H as Appendices J
+ and K, respectively;
+* Add normative reference to RFC2046, MIME Media Types;
+* Add normative reference to RFC3023, XML Media Types;
+* Change description of implied begin/end on <tt/> to refer to

+ interval;
+* In 9.1.2, indicate that begin/end points specified on <region/>
+ are relative to the time interval of the nearest ancestor associated
+ with a time interval;
+* In 9.1.2, remove constraint that if no tts:extent is specified in
+ computed style set then no content is flowed into region; this
+ constraint is redundant since the initial value of tts:extent is
+ "auto" which is defined to be extent of root container;
+* Fix typos:
+ + section 9.1.2, s/layout/region/ in para describing dur attribute;
+* Add note at end of the preamble to section 8.2, [Styling] Attribute

+ property may be specified on any content element independently of
+ whether it applies to that element;
+* Remove note in 7.1.7 that indicated that <br/> is empty in
+ the reduced XML infoset, which no longer holds as both metadata and
+ animation children may be present;

+* Add definition of implicit duration of document instance in section 7.1.1;
+* In definition of <time-expression> syntax in section 10.3.1,
+ remove paragraph referring to default time metric, which no longer
+ applies now that time metric must be specified;
+* In Appendix I, add table I-2 with attribute vocabulary derivation;
+* Add definition of percentage lengths to each style property
+ definition. Percentages apply to the following styles: extent,
+ fontSize, lineHeight, origin, padding, and textOutline;
+* Fill in Appendix I with QA Framework compliance information;
+* Add section 5.3.2 defining a presently empty "Extension Catalog"
+ that serves as a placeholder for future standardized extensions and
+ additionally specifies that document instance may contain arbitrary
+ namespace qualified elements and attributes from other namespaces;
+* Add section 3.3 defining conformance claims and requirements
+ regarding for providing an implementation compliance statement;
+* Add hyperlinks throughout document for references to elements,
+ attributes, and value expressions;
+* Add new Appendix F containing sample code and sample compile,
+ load, run session transcript;
+* Change IDREF to IDREFS as value of ttm:agent as found in prose in
+ section 12.2.1;

+
+The following changes result in a technical change of the conformance
+criteria, the normative abstract document type that is defined
+for use with DFXP, or the defined value space of an attribute or
+property:
+
+* Restore support for nested div and span elements [that had
+ been removed in an early working draft].
+* Change "id" attribute to "xml:id".
+* Add tts:textDecoration style property.
+* Update namespace URIs to use 2006/10 instead of 2006/04.
+* Update profile URIs to use 2006/10 instead of 2006/04.
+
+<phrase role="strong">Editorial Changes</phrase>
+
+The following changes are editorial in nature or entail semantic
+clarifications that do not affect the abstract document type, defined
+schemas, or conformance criteria for DFXP:
+
+* Update "status of this document" (SOTD) section to
+ reflect CR transition.
+* Add normative reference to xml:id recommendation.
+* Add note in section 9.3.3 indicating that intermediate document
+ examples are internal processing states and do not represent
+ valid DFXP documents.
+* Add "Except for transparent, " to note in section 8.3.12.
+* Add recommendation, in section 3.1 item 5, that conformant
+ reduced infoset "should" adhere to WCAG1.0.
+* Add normative reference to WCAG1.0.
+* Update informative reference to SVG1.0 to reference SVG1.1
+ instead.
+* Insert new (normative) Appendix D that specifies the
+ MIME Media Type registration information for application/ttaf+xml.
+* Add normative reference to RFC3023 tagged as [XML Media Types],
+ for use by new Appendix D.
+* Normalize and add missing dates of W3C Recs cited in
+ Appendices E (References) and F (Other References).
+* In Table 4, express groups as choice lists instead of
+ sequences (which might have been confusing).
+* Revise content models of XML Representation of div, p,
+ and span element information items in order to make
+ reference to Block.class and Inline.class element
+ groups.
+* Add "This appendix is normative" to beginning of each
+ normative appendix.
+* Add clarifications in sections 8.3.13 and 8.3.14 that
+ syntactic element "char" adheres to production [2] of
+ XML1.1, while syntactic element "S" adheres to
+ production [3] of XML1.1.
+* Add note to section 7.1.7 (and rearrange paragraph ordering)
+ to indicate that two <br> elements are intended to
+ produce two forced line breaks in a sequence.
+* Add note to section 6.2.4 that indicates that PAL
+ formatted video nominally uses a 1:1 frame rate multiplier
+ (except for PAL/M).
+* Add note to end of section 9.3.2 that indicates that a
+ compliant XSL1.0 presentation processor may be insufficient
+ to satisfy the presentation semantics of DFXP.
+* Clarify syntax of <alpha> style value expression to
+ use XML Scheme Datatype lexical representation of xs:float,
+ which was the intended syntactic value space for this
+ expression.
+* Clarify that ttp:cellResolution columns or rows must not be zero
+ if present.
+* Clarify that ttp:frameRate must be greater than zero if present.
+* Clarify that ttp:frameRateMultipler denominator must not be zero
+ if present. Correct misspelling "demoninator".
+* Clarify that ttp:pixelAspectRatio width or height must not be zero
+ if present.
+* Clarify that ttp:subFrameRate must not be zero if present.
+* Clarify that ttp:tickRate must not be zero if present.
+* Remove superfluous end tag close (>) in XML representation of
+ metadata element information item in section 12.1.1.
+* Add clarification that the declared value of an inline style
+ attribute on body, region, and style elements must not be "inherit".
+* Add clarification in section 8.5.1 item 2 that use of value
+ "inherit" does not apply if element is body element.
+* Clarify that tt element establishes the root stacking context
+ for the purpose of interpreting the tts:zIndex style property;
+ this corresponds with the prescribed mapping of tt:tt to fo:root
+ as described in section 9.3.2 item 3.
+* Clarify that ttp:{markerMode,smpteMode,tickRate,timeBase} are
+ significant only when specified on tt element.
+* Add note at end of section 8.2.17 that padding style attribute
+ is based on XSL 1.0 shorthand "padding" property except that
+ the individual values map to writing mode relative padding
+ properties, i.e., padding-before, padding-after, etc.
+* Update attribute derivation table (Appendix I.2) to reflect
+ addition of tts:textDecoration and change from id to xml:id.
+* Update publishing date and dates in SOTD CR publication.
+* Update SOTD to remove use of sample code as satisfying 2
+ implementation convention for exit criteria. Note that sample
+ code can still serve as 1 implementation of 2 required.
+* Add paragraph to SOTD describing unsatisfied comments during
+ first LC.
+* Change "reference code" to read "sample code".

+
+ ChangeLog: (See also: CVS ChangeLog)
+
+ 15 August 2002: Norman Walsh, <Norman.Walsh@Sun.COM>
+ - Version 1.3 released at http://www.w3.org/2002/xmlspec/html/1.3/xmlspec.xsl
+ There have never been any "official" releases before, so the version number
+ is arbitrary.
+
+ 15 August 2001: Hugo Haas <hugo@w3.org>
+ - Slightly modified the status sentence introducing editors'
+ copies.
+ - Now using role to distinguish editors' copies: e.g.
+ <spec w3c-doctype="wd" role="editors-copy">
+
+ 14 August 2001: Hugo Haas <hugo@w3.org>
+ - If w3c-doctype is not a W3C TR, do not use a Note style
+ sheet, use <http://www.w3.org/StyleSheets/TR/base.css>
+ instead.
+ - If the other-doctype is "editors-copy", do not use the W3C
+ logo and mark the document as such in the status section.
+
+ 12 Jun 2001: (Norman.Walsh@Sun.COM)
+ - Support non-tabular examples. If tabular.examples is non-zero,
+ tables will be used for examples, otherwise nested divs and
+ CSS will be used. tabular.examples is *zero* by default.
+
+ 06 Jun 2001: (Norman.Walsh@Sun.COM)
+ - Support copyright element in header; use the content of that
+ element if it is present, otherwise use the auto-generated
+ copyright statement.
+
+ 15 May 2001: (Norman.Walsh@Sun.COM)
+ - Changed copyright link to point to dated IPR statement:
+ http://www.w3.org/Consortium/Legal/ipr-notice-20000612
+
+ 25 Sep 2000: (Norman.Walsh@East.Sun.COM)
+ - Sync'd with Eve's version:
+ o Concatenated each inline element's output all on one line
+ to avoid spurious spaces in the output. (This is really an
+ IE bug, but...) (15 Sep 2000)
+ o Updated crism's email address in header (7 Sep 2000)
+ o Changed handling of affiliation to use comma instead of
+ parentheses (9 Aug 2000)
+
+ 14 Aug 2000: (Norman.Walsh@East.Sun.COM)
+
+ - Added additional.title param (for diffspec.xsl to change)
+ - Fixed URI of W3C home icon
+ - Made CSS stylesheet selection depend on the w3c-doctype attribute
+ of spec instead of the w3c-doctype element in the header
+
+ 26 Jul 2000: (Norman.Walsh@East.Sun.COM)
+
+ - Improved semantics of specref. Added xsl:message for unsupported
+ cases. (I'm by no means confident that I've covered the whole
+ list.)
+ - Support @role on author.
+ - Make lhs/rhs "code" in EBNF.
+ - Fixed bug in ID/IDREF linking.
+ - More effectively disabled special markup for showing @diffed
+ versions
+
+ 21 Jul 2000: (Norman.Walsh@East.Sun.COM)
+
+ - Added support for @diff change tracking, primarily through
+ the auxiliary stylesheet diffspec.xsl. However, it was
+ impractical to handle some constructions, such as DLs and TABLEs,
+ in a completely out-of-band manner. So there is some inline
+ support for @diff markup.
+
+ - Added $additional.css to allow downstream stylesheets to add
+ new markup to the <style> element.
+
+ - Added required "type" attribute to the <style> element.
+
+ - Fixed pervasive problem with nested <a> elements.
+
+ - Added doctype-public to xsl:output.
+
+ - Added $validity.hacks. If "1", then additional disable-output-escaping
+ markup may be inserted in some places to attempt to get proper,
+ valid HTML. For example, if a <glist> appears inside a <p> in the
+ xmlspec source, this creates a nested <dl> inside a <p> in the
+ HTML, which is not valid. If $validity.hacks is "1", then an
+ extra </p>, <p> pair is inserted around the <dl>.
+
+ 5 June 2001, Henry S. Thompson (ht@cogsci.ed.ac.uk)
+
+ - Fixed a link in copyright boilerplate to be dated

+ <h2><a name="intro" id="intro"></a>1 Introduction</h2>
+ <p>This document specifies usage scenarios and requirements for a timed text
+ authoring format. A timed text authoring format is a content type that represents
+ timed text media for the purpose of interchange among authoring systems. Timed
+ text is textual information that is intrinsically or extrinsically associated
+ with timing information.</p>
+ <div class="note">
+ <p class="prefix"><b>Note:</b></p>
+ <p>This document incorporates requirements regarding stylistic and timing
+ functionality that range from simple to relatively complex. It is expected that
+ the use of this functionality will be partitioned into one or more profiles
+ represented by document types of increasing complexity. It is not expected that
+ every authoring system or ultimate consumer of timed text content will support
+ all of this functionality.</p>
+ </div>
+ <div class="div2">
+ <h3><a name="motivation" id="motivation"></a>1.1 Motivation</h3>
+ <p>A principal motivation for the development of a common authoring format for
+ timed text is the lack of a standard content format that supports the
+ representation and interchange of textual information which is synchronized
+ with other media elements or which serves as a synchronization master
+ itself.</p>
+ <p>Popular proprietary multimedia systems and their corresponding player
+ components have defined distinct timed text formats for each proprietary use.
+ As a consequence there is no common authoring format that serves as a portable
+ interchange format between such systems. A goal of the present work is to
+ define such a portable interchange format to ease the burden of authoring tool
+ developers and users as well as enhance portability of timed text content.</p>
+ <p>A side effect of the development and deployment of a common timed text
+ authoring format is that it simplifies the creation and distribution of
+ synchronized text for use with a multitude of devices, such as multimedia
+ players, caption, subtitle, and teletext encoders and decoders, character
+ generators, LED displays, and other text display devices.</p>
+ </div>
+ <div class="div2">
+ <h3><a name="model" id="model"></a>1.2 System Model</h3>
+ <p>The uses cases and requirements specified in this document are based upon a
+ system model, depicted in <a href="#model-graphic"><b>Figure 1 – System
+ Model</b></a>, wherein the timed text authoring format serves as a
+ bidirectional interchange format among a heterogeneous collection of authoring
+ systems, and as a unidirectional interchange format to a heterogeneous
+ collection of distribution formats after undergoing transcoding to the target
+ distribution formats as required.</p>

+ existing legacy formats, and which may also be distributed directly.</p>
+ </div>

+<head>Introduction</head>
+<p>This document specifies usage scenarios and requirements for a timed text authoring
+format. A timed text authoring format is a content type that represents timed text
+media for the purpose of interchange among authoring systems.
+Timed text is textual information that is intrinsically or extrinsically
+associated with timing information.</p>
+<note role="explanation">
+<p>This document incorporates requirements regarding stylistic
+and timing functionality that range from simple to relatively complex. It is expected
+that the use of this functionality will be partitioned into one or more profiles
+represented by document types of increasing complexity. It is not expected that every
+authoring system or ultimate consumer of timed text content will support all of this
+functionality.</p>
+</note>
+<div2 id="motivation">
+<head>Motivation</head>
+<p>A principal motivation for the development of a common authoring format for
+timed text is the lack of a standard content format that supports the representation
+and interchange of textual information which is synchronized with other media
+elements or which serves as a synchronization master itself.</p>
+<p>Popular proprietary multimedia systems and their corresponding player
+components have defined distinct timed text formats for each proprietary use. As
+a consequence there is no common authoring format that serves as a
+portable interchange format between such systems. A goal of the present work is
+to define such a portable interchange format to ease the burden of authoring tool
+developers and users as well as enhance portability of timed text content.</p>
+<p>A side effect of the development and deployment of a common timed text authoring
+format is that it simplifies the creation and distribution of synchronized text
+for use with a multitude of devices, such as multimedia players, caption, subtitle,
+and teletext encoders and decoders, character generators, LED displays, and other
+text display devices.</p>
+</div2>
+<div2 id="model">
+<head>System Model</head>
+<p>The uses cases and requirements specified in this document are based upon a system
+model, depicted in <specref ref="model-graphic"/>, wherein the timed text authoring format
+serves as a bidirectional interchange format among a heterogeneous collection of
+authoring systems, and as a unidirectional interchange format to a
+heterogeneous collection of distribution formats after undergoing transcoding
+to the target distribution formats as required.</p>

+<note role="explanation">
+<p>In the figure depicted above, the acronym <emph>DFXP</emph> refers
+to a profile of the timed text authoring format known as the Distribution
+Format Exchange Profile, which is intended primarily to satisfy
+interchange among existing legacy formats, and which may also be
+distributed directly.</p>
+</note>
+<note role="explanation">
+<p>This system model does not preclude the timed text authoring format from
+being used as a distribution format in its own right.</p>

+<p>The distinction between <emph>captioning</emph> and <emph>subtitling</emph> is best
+expressed as follows: captioning is expressly intended to serve the needs of deaf and

+in contrast, subtitling is generally intended to serve the needs of hearing users who
+don't have access to an audio track (e.g., in muting situations) or don't understand
+the natural language of the speech contained in the audio track. Subtitling is often
+viewed as a paraphrase or a translation of speech information, as opposed to a transcription of
+all audio information.</p>
+<p>In the absence of captioning information, subtitling information may also be
+used by deaf and hard of hearing

+
+ ChangeLog: (See also: CVS ChangeLog)
+
+ 15 August 2002: Norman Walsh, <Norman.Walsh@Sun.COM>
+ - Version 1.3 released at http://www.w3.org/2002/xmlspec/html/1.3/xmlspec.xsl
+ There have never been any "official" releases before, so the version number
+ is arbitrary.
+
+ 15 August 2001: Hugo Haas <hugo@w3.org>
+ - Slightly modified the status sentence introducing editors'
+ copies.
+ - Now using role to distinguish editors' copies: e.g.
+ <spec w3c-doctype="wd" role="editors-copy">
+
+ 14 August 2001: Hugo Haas <hugo@w3.org>
+ - If w3c-doctype is not a W3C TR, do not use a Note style
+ sheet, use <http://www.w3.org/StyleSheets/TR/base.css>
+ instead.
+ - If the other-doctype is "editors-copy", do not use the W3C
+ logo and mark the document as such in the status section.
+
+ 12 Jun 2001: (Norman.Walsh@Sun.COM)
+ - Support non-tabular examples. If tabular.examples is non-zero,
+ tables will be used for examples, otherwise nested divs and
+ CSS will be used. tabular.examples is *zero* by default.
+
+ 06 Jun 2001: (Norman.Walsh@Sun.COM)
+ - Support copyright element in header; use the content of that
+ element if it is present, otherwise use the auto-generated
+ copyright statement.
+
+ 15 May 2001: (Norman.Walsh@Sun.COM)
+ - Changed copyright link to point to dated IPR statement:
+ http://www.w3.org/Consortium/Legal/ipr-notice-20000612
+
+ 25 Sep 2000: (Norman.Walsh@East.Sun.COM)
+ - Sync'd with Eve's version:
+ o Concatenated each inline element's output all on one line
+ to avoid spurious spaces in the output. (This is really an
+ IE bug, but...) (15 Sep 2000)
+ o Updated crism's email address in header (7 Sep 2000)
+ o Changed handling of affiliation to use comma instead of
+ parentheses (9 Aug 2000)
+
+ 14 Aug 2000: (Norman.Walsh@East.Sun.COM)
+
+ - Added additional.title param (for diffspec.xsl to change)
+ - Fixed URI of W3C home icon
+ - Made CSS stylesheet selection depend on the w3c-doctype attribute
+ of spec instead of the w3c-doctype element in the header
+
+ 26 Jul 2000: (Norman.Walsh@East.Sun.COM)
+
+ - Improved semantics of specref. Added xsl:message for unsupported
+ cases. (I'm by no means confident that I've covered the whole
+ list.)
+ - Support @role on author.
+ - Make lhs/rhs "code" in EBNF.
+ - Fixed bug in ID/IDREF linking.
+ - More effectively disabled special markup for showing @diffed
+ versions
+
+ 21 Jul 2000: (Norman.Walsh@East.Sun.COM)
+
+ - Added support for @diff change tracking, primarily through
+ the auxiliary stylesheet diffspec.xsl. However, it was
+ impractical to handle some constructions, such as DLs and TABLEs,
+ in a completely out-of-band manner. So there is some inline
+ support for @diff markup.
+
+ - Added $additional.css to allow downstream stylesheets to add
+ new markup to the <style> element.
+
+ - Added required "type" attribute to the <style> element.
+
+ - Fixed pervasive problem with nested <a> elements.
+
+ - Added doctype-public to xsl:output.
+
+ - Added $validity.hacks. If "1", then additional disable-output-escaping
+ markup may be inserted in some places to attempt to get proper,
+ valid HTML. For example, if a <glist> appears inside a <p> in the
+ xmlspec source, this creates a nested <dl> inside a <p> in the
+ HTML, which is not valid. If $validity.hacks is "1", then an
+ extra </p>, <p> pair is inserted around the <dl>.
+
+ 5 June 2001, Henry S. Thompson (ht@cogsci.ed.ac.uk)
+
+ - Fixed a link in copyright boilerplate to be dated
