+      This specification defines an element-based markup for defining
+      animation and time-related changes to a Web page.
+      It is intended to replace the animation features of <a
+      href="http://www.w3.org/TR/SVG11/">SVG 1.1</a> by building on the model
+      defined in <a href="http://www.w3.org/TR/web-animations/">Web
+      Animations</a>.

+
+    <section>
+      <h2>Introduction</h2>
+      <p class="todo">TBD</p>
+      <section class="informative">
+        <h2>Use cases</h2>
+        <h4>Tweening and cutout animation</h4>
+        <p>
+          A common animation technique involves taking some graphical elements
+          and interpolating their properties such as position or color or moving
+          them along a path.
+          This is sometimes referred to as <em>cutout animation</em> since the
+          moving parts were traditionally represented by separate shapes cut
+          from cardboard or similar material.
+        </p>
+        <p>
+          For example, in the following segment of a cartoon, a golfer swings
+          his arms (and club!) and as a result the golf ball follows
+          a trajectory through the air before bouncing along the ground.
+        </p>
+        <pre class='example sh_html'>
+&lt;path id="golferBody" d="&hellip;"/&gt; 
+&lt;g id="armsAndClub"&gt;
+  &lt;path id="club" d="&hellip;"/&gt; 
+  &lt;path id="arms" d="&hellip;"/&gt; 
+&lt;/g&gt;
+&lt;circle id="ball" &hellip;/&gt;
+&lt;seq&gt;
+  &lt;!-- Rotate man's arms and club --&gt;
+  &lt;animate href="armsAndClub" attributeName="transform"
+    values="rotate(0); rotate(-120); rotate(30); rotate(0)"
+    keyTimes="0; 0.5; 0.8; 1" additive="sum" dur="1.2s"/&gt;
+  &lt;!-- Show course of ball --&gt;
+  &lt;animateMotion href="ball" begin="-0.312s" path="&hellip;"/&gt;
+&lt;/seq&gt;
+        </pre>
+        <h4>Timesheets</h4>
+        <p>
+          In simple examples such as the above cartoon, it is useful to
+          represent graphical content and timing side-by-side.
+          However, for applications that involve complex sequencing of effects
+          it is often convenient to separate the temporal markup into a separate
+          subtree or document sometimes referred to as
+          a &ldquo;timesheet&rdquo;&mdash;the temporal equivalent of
+          a stylesheet.
+        </p>
+        <p>
+          Such a timesheet may define animations directly or simply set classes
+          and define the animation effects using, for example, CSS Animations
+          [[CSS3-ANIMATIONS]].
+        </p>
+        <p>
+          For example, the title screen and first scene of an interactive
+          story might use the following timesheet:
+        </p>
+        <pre class='example sh_html'>
+&lt;!-- Title screen --&gt;
+&lt;seq begin="0s"&gt;
+  &lt;!-- Draw curtains to the side --&gt;
+  &lt;par&gt;
+    &lt;animate href="leftCurtain" attributeName="transform"
+      to="translate(-100 0)" dur="1s" additive="sum"/&gt;
+    &lt;animate href="rightCurtain" attributeName="transform"
+      to="translate(100 0)" dur="1s" additive="sum"/&gt;
+  &lt;/par&gt;
+  &lt;!-- Then show the title by setting a class which may trigger,
+       for example, a fade animation defined in CSS --&gt;
+  &lt;set href="title" attributeName="class" to="active"/&gt;
+&lt;/seq&gt;
+
+&lt;!-- Show the first scene when the user clicks the title screen --&gt;
+&lt;seq begin="titleScreen.click" restart="whenNotActive"&gt;
+  &lt;!-- Cross fade to show background --&gt;
+  &lt;par&gt;
+    &lt;animate href="titleScreen" attributeName="opacity" to="0" dur="1s"/&gt;
+    &lt;animate href="scene1Background" attributeName="opacity" to="1" dur="1s"/&gt;
+  &lt;/par&gt;
+  &lt;!-- Move narrator onstage --&gt;
+  &lt;animate href="narrator" attributeName="transform"
+    to="translate(180 90)" dur="0.3s"/&gt;
+  &lt;!-- Set the active class on the narrator which may trigger further
+       animations or perhaps update the pointer-events property so he
+       becomes clickable--&gt;
+  &lt;set href="narrator" attributeName="class" to="active"/&gt;
+&lt;/seq&gt;
+        </pre>
+        <p>
+          The triggers for these effects can be defined declaratively as in
+          the example above or they can be applied using script (see the
+          <code>beginElement</code> and <code>beginElementAt</code> methods).
+        </p>
+        <div class="feedbackWanted">
+          <p>
+            For more complex usage such as an interactive comic book the
+            following features would be useful:
+          </p>
+          <ul>
+            <li>Ability to define a &ldquo;sequence&rdquo; (which may or may not
+                be a type of <code>&lt;seq&gt;</code>) where each step is
+                gated on certain conditions (e.g. mouse clicks or keyboard
+                presses).
+            <li>Ability to step backwards through such a sequence.
+            <li>Ability to define alternative animations when stepping
+                backwards.
+            <li>Ability to step forwards causing the current in-play step to
+                skip to its end and triggering the next step.
+            <li>Ability to hyperlink to a particular step (including when steps
+                when such steps are nested)
+          </ul>
+          <p>
+            The features currently defined in this specification can be used to
+            realize some of these sort of use cases but typically it is
+            quite cumbersome.
+          </p>
+          <p>
+            It is possible to extend this specification to cover the above
+            features or we can defer it and introduce a more fully-featured
+            state tracking feature in a subsequent version.
+          </p>
+        </div>
+        <h4>Round-trip ad-hoc animation</h4>
+        <p>
+          When performing DOM manipulation, it is often useful to attach
+          animation to an element in such a form that it can be serialized for
+          later playback and editing.
+        </p>
+        <p>
+          For example, a presentation authoring tool allows a user to select
+          items on a slide and tween their various properties at different times
+          or in response to events such as mouse clicks.
+          This could be achieved by annotating the element in question with
+          a child element as follows:
+        </p>
+        <pre class='example sh_html'>
+&lt;image&gt;
+  &lt;animate begin="3s" dur="1s" attributeName="opacity" to="1" fill="forwards"/&gt;
+&lt;/image&gt;
+        </pre>
+        <p>
+          In many cases, such an approach is easier to generate and re-parse
+          than doing so with stylesheet animation:
+        </p>
+        <pre class='example sh_html'>
+&lt;image&gt;
+  &lt;style scoped&gt;
+    image {
+      animation: fadeIn 1s 3s forwards;
+    }
+    @keyframes fadeIn {
+      to {
+        opacity: 1.0;
+      }
+    }
+  &lt;/style&gt;
+&lt;/image&gt;
+        </pre>
+        <h4>Frame-based animation</h4>
+        <p>
+          Rather than smoothly tweening values, sometimes it is desirable to
+          overlay a series of independent images in quick succession.
+        </p>
+        <p>
+          For example, a children's workshop teaching animation principles
+          allows children to draw a series of similar images and then show and
+          hide them in turn creating the illusion of movement.
+        </p>
+        <p>
+          Supposing each drawn image is contained in an SVG
+          <code>&lt;g&gt;</code> element, the animation could be produced as
+          follows:
+        </p>
+        <pre class='example sh_html'>
+  &lt;!-- Graphical content --&gt;
+  &lt;g class="frame" visibility="hidden"&gt;&hellip;&lt;/g&gt;
+  &lt;g class="frame" visibility="hidden"&gt;&hellip;&lt;/g&gt;
+  &lt;g class="frame" visibility="hidden"&gt;&hellip;&lt;/g&gt;
+  &lt;g class="frame" visibility="hidden"&gt;&hellip;&lt;/g&gt;
+
+  &lt;!-- Timing --&gt;
+  &lt;seq repeatCount="indefinite"&gt;
+    &lt;set select=".frame" dur="0.2s" attributeName="visibility" to="visible"/&gt;
+  &lt;/seq&gt;
+        </pre>
+        <h4>Animated user interface widgets</h4>
+        <p>
+          User interface widgets are often accompanied by animated effects that
+          provides affordances to the user.
+          These effects should be defined in a manner that allows re-use across
+          a variety of similar widgets.
+        </p>
+        <p>
+          For example, following is a re-usable definition of mouse hover
+          effects applied to some content representing a button.
+        </p>
+        <pre class='example sh_html'>
+&lt;!-- A button-like object --&gt;
+&lt;g role="button"&gt;
+  &lt;rect &hellip; /&gt;
+  &lt;text filter="child"&gt;
+    &lt;filter &hellip; /&gt;&hellip;&lt;feGaussianBlur &hellip; /&gt;&lt;/filter&gt;
+    Button label
+  &lt;/text&gt;
+&lt;/g&gt;
+
+&lt;!-- A complex mouseover effect --&gt;
+&lt;par select="g[role=button]" begin="mouseover" end="mouseout"&gt;
+  &lt;!-- Tween background color of button --&gt;
+  &lt;animate select="rect" attributeName="fill" to="blue" dur="0.3s" fill="forwards"/&gt;
+  &lt;seq&gt;
+    &lt;!-- Wiggle text to the side --&gt;
+    &lt;animate select="text" attributeName="transform" dur="0.3s"
+      additive="sum" values="translate(0); translate(-10); translate(0)"/&gt;
+    &lt;!-- Then make it glow by tweaking part of the filter --&gt;
+    &lt;animate select="feGaussianBlur" attributeName="stdDeviation"
+      from="0" to="2" fill="forwards" dur="0.3s"/&gt;
+  &lt;/seq&gt;
+&lt;/par&gt;
+
+&lt;!-- Fade out button background on mouseout --&gt;
+&lt;par select="g[role=button]" begin="mouseout" end="mouseover; indefinite"&gt;
+  &lt;animate select="rect" begin="mouseout" attributeName="fill"
+    to="navy" dur="0.3s" fill="forwards"/&gt;
+  &lt;set select="feGaussianBlur" attributeName="stdDeviation" to="0"/&gt;
+&lt;/par&gt;
+        </pre>
+        <div class="annotation">
+          This use case would also benefit from the custom reversing suggested
+          for timesheets / interactive comics.

+        <h2>Relationship to SVG 1.1 Animation</h2>
+        <p>
+          This specification is intended to be backwards-compatible with the
+          animation features defined in SVG 1.1 Second Edition [[SVG11]] with
+          the following exceptions:
+        </p>
+        <ul>
+          <li>The special behavior of a frozen to-animation has been altered to
+              follow the regular behavior of the model since no user agent
+              implemented the specified behavior.
+          <li>The procedure for resolving syncbase dependencies and particularly
+              breaking cyclic dependencies has been rewritten in a manner that
+              may produce slight variations in some circumstances.
+              This was done because the previous definition was incredibly vague
+              and as a result was implemented inconsistently in every user
+              agent.
+          <li>The <span class="elem">animateColor</span> element has been
+              removed since it was deprecated in SVG 1.1.
+        </ul>
+        <p>
+          The following features defined in SVG 1.1 have been deprecated in this
+          specification:
+        </p>
+        <ul>
+          <li>The <span class="elem">animateTransform</span> element.
+              This is because the <span class="elem">animate</span> element is
+              now able to animate transform lists which produces more
+              predictable behavior that avoids many of the issues surrounding
+              <span class="elem">animateTransform</span>.
+        </ul>
+        <p>
+          The following additional features not present in SVG 1.1 have been
+          added to this specification:
+        </p>
+        <ul>
+          <li>All features are now defined in terms of the Web Animations
+              [[web-animations]] model providing a consistent foundation for
+              applications also using CSS-based animations or the Web Animations
+              API.
+              This also makes it possible for the author to programmatically
+              inspect and modify the animations generated by the markup defined
+              in this specification.
+          <li>The <span class="elem">par</span> and
+              <span class="elem">seq</span> elements have been introduced to
+              provide more powerful synchronization behavior that avoids many of
+              the problems associated with syncbase timing such as being unable
+              to cancel a chain of animations or seek a document in constant
+              time.
+              These elements also facilitate re-use of complex animation
+              definitions.
+          <li>Animation elements now include the <span
+              class="attr">select</span> attribute for targetting a range of
+              elements making animations re-useable
+              (see <a
+              href="#attributes-to-identify-the-target-elements-for-a-timed-element"
+              class="sectionRef"></a>).
+          <li>The <span class="attr">href</span> attribute no longer requires
+              the XLink namespace in keeping with changes made in SVG 2.0
+              (see <a
+              href="#attributes-to-identify-the-target-elements-for-a-timed-element"
+              class="sectionRef"></a>).
+          <li>The <span class="attr">cancel</span> attribute has been added to
+              completely remove an animation or a group of animations including
+              fill effects when its conditions are met.
+          <li>The <span class="attr">reverse</span> attribute has been added to
+              specify conditions that cause and animation or a group of
+              animations to change direction.
+          <li>The <span class="attr">repeatStart</span> attribute has been added
+              to allow starting an animation part-way through its interval.
+          <li>The <span class="attr">playback-rate</span> attribute has been
+              added to control the playback rate of animations and groups
+              including reversing them.
+          <li>The <span class="attr">direction</span> attribute has been added
+              to allow controlling the direction of alternate iterations of
+              animations and groups.
+          <li>The <span class="attr">easing</span> and <span
+              class="attr">easing-times</span> attributes have been added to

+        <p>
+          The Media Fragments specification [[!MEDIA-FRAGMENTS]] defines a means
+          for addressing a temporal range of a media resource.
+          The application of the temporal parameters to documents with the <a
+          href="http://www.w3.org/TR/SVG/intro.html#MIMEType">SVG MIME type</a> 
+          [[!SVG11] is as follows.
+        </p>
+        <ul>
+          <li>If there is a begin time, seek the document controller to
+              the begin time at the earliest of two moments: when the document
+              begins to play or document load.
+              <p class="note">
+                Note that seeking behavior is well-defined even when the
+                document has yet to start.
+              </p>
+          </li>
+          <li>If there is an end time, set a flag on the controller to say
+              auto-pause at the given time.</li>
+          <li>Any calls to seek / pause / play etc. on that controller clear the
+              flag.</li>
+          <li>If the controller reaches (or passes) the end time and the flag is
+              still set, call pause and clear the flag.</li>
+        </ul>
+        <p class="todo">
+          What happens if the fragment is changed after the document has loaded
+        </p>
+        <p class="note">
+          Note that media fragments are defined to operate on resources based on
+          their MIME type.
+          As a result, temporal addressing may not have any effect for SVG
+          content that is served in a document with a MIME type other than the
+          SVG MIME type such as SVG embedded in HTML.
