    <h4>7.2.2 <a id="wide-review">Wide Review</a></h4>
    <p>The requirements for wide review are not precisely defined by the
      process. The objective is to ensure that the entire set of stakeholders of
      the Web community, including the general public, have had adequate notice
      of the progress of the Working Group and thereby an opportunity to comment
      on the specification. Before approving transitions, the Director will
      consider who has actually reviewed the document and provided comments,
      particularly in light of the listed dependencies, and how the Working
      Group has solicited and responded to review. In particular, the Director
      is likely to consider the record of requests to and responses from groups
      identified as dependencies in the charter, as well as seeking evidence of
      clear communication to the general public about appropriate times and
      which content to review. </p>
    <p>As an example, inviting review of new or significantly revised sections
      published in Heartbeat Working Drafts, and tracking those comments and the
      Working Group's responses, is generally a good practice which would often
      be considered positive evidence of wide review. A recommended practice is
      making a specific announcement to other W3C Working Groups as well as the
      general public that a group proposes to enter Last Call Candidate
      Recommendation in e.g. approximately four weeks, . By contrast a generic
      statement in a document requesting review at any time is likely not to be
      considered as sufficient evidence that the group has solicited wide
      review. </p>
    <p>A Working Group could present evidence that wide review has been
      received, irrespective of solicitation. But it is important to note that
      receiving many detailed reviews is not necessarily the same as wide
      review, since they may only represent comment from a small segment of the
      relevant stakeholder community.</p>
    <h4 id="implementation-experience">7.2.3 Implementation Experience</h4>
    <p>Implementation experience is required to show that a specification is
      sufficiently clear, complete, and relevant to market needs that
      independent interoperable implementations of each feature of the
      specification will be realized. While no exhaustive list of requirements
      is provided here, when assessing that there is adequate implementation
      experience the Director will consider (though not be limited to):</p>
    <ul>
      <li>is each feature implemented, and how is this demonstrated; (for
        example, is there a test suite)?</li>
      <li>are there independent interoperable implementations?</li>
      <li>are there implementations created by other than the authors of the

+        Patent Policy</a> [<a href="http://www.w3.org/2005/10/Process-20051014/refs.html#ref-patentpolicy">PUB33</a>].</p>
    <h3>7.6 <a name="rec-modify" id="rec-modify">Modifying a W3C Recommendation</a></h3>
    <p>The following sections discuss the management of errors and the process
      for making normative changes to a Recommendation.</p>
    <h4>7.6.1 <a name="errata" id="errata">Errata Management</a></h4>
    <p>Tracking errors is an important part of a Working Group's ongoing care of
      a
      Recommendation; for this reason, the scope of a Working Group charter
      generally
      allows time for work after publication of a Recommendation. In this
      Process
      Document, the term "erratum" (plural "errata") refers to any class of
      mistake,
      from mere editorial to a serious error that may affect the conformance
      with the
      Recommendation by software or content (e.g., content validity).
      <strong>Note:</strong> Before a document becomes a Recommendation, the W3C
      Process focuses on <a href="#substantive-change">substantive changes</a>
      (those
      related to prior reviews). After a document has been published as
      Recommendation, the W3C Process focuses on those changes to a technical
      report
      that might affect the conformance of content or deployed software.</p>
    <p>Working Groups <span class="rfc2119">MUST</span> track errata on an
      "errata
      page." An errata page is a list of enumerated errors, possibly accompanied
      by
      corrections. Each Recommendation links to an errata page; see the Team's
      <a href="http://www.w3.org/Guide/pubrules">Publication Rules</a>.</p>
    <p>A correction is first "proposed" by the Working Group. A correction
      becomes
      normative -- of equal status as the text in the published Recommendation
      --
      through one of the processes described below. An errata page <span class="rfc2119">MAY</span>
      include both proposed and normative corrections. The
      Working Group <span class="rfc2119">MUST</span> clearly identify which
      corrections are proposed and which are normative.</p>
    <p>A Working Group <span class="rfc2119">SHOULD</span> keep their errata
      pages
      up-to-date, as errors are reported by readers and implementers. A Working
      Group
      <span class="rfc2119">MUST</span> report errata page changes to interested
      parties, notably when corrections are proposed or become normative,
      according
      to the Team's requirements. For instance, the Team might set up a mailing
      list
      per Recommendation where a Working Group reports changes to an errata
      page.</p>
    <h4>7.6.2 <a name="correction-classes" id="correction-classes">Classes of
        Changes to a Recommendation</a></h4>
    <p>This document distinguishes the following classes of changes to a
      Recommendation.</p>
    <dl>
      <dt>1. No changes to text content</dt>
      <dd>These changes include fixing broken links or invalid markup.</dd>
      <dt>2. Corrections that do not affect conformance</dt>
      <dd>Editorial changes or clarifications that do not change the technical
        content of the specification.</dd>
      <dt>3. Corrections that <span class="rfc2119">MAY</span> affect
        conformance,
        but add no new features</dt>
      <dd>These changes <span class="rfc2119">MAY</span> affect conformance to
        the
        Recommendation. A change that affects conformance is one that:
        <ol>
          <li>turns conforming data, processors, or other conforming agents into
            non-conforming agents, or</li>
          <li>turns non-conforming agents into conforming ones, or</li>
          <li>clears up an ambiguity or under-specified part of the
            specification in such
            a way that an agent whose conformance was once unclear becomes
            clearly
            conforming or non-conforming.</li>
        </ol>
      </dd>
      <dt>4. New features</dt>
    </dl>
    <p>The first two classes of change require no technical review of the
      proposed
      changes, although a Working Group <span class="rfc2119">MAY</span> issue
      a Call
      for Review. The modified Recommendation is published according to the
      Team's
      requirements, including <a href="http://www.w3.org/Guide/pubrules">Publication
        Rules</a> [<a href="refs.html#ref-pubrules">PUB31</a>].</p>
    <p>For the third class of change, W3C requires:</p>
    <ol>
      <li>Review by the community to ensure the technical soundness of proposed
        corrections.</li>
      <li>Timely publication of the edited Recommendation, with corrections
        incorporated.</li>
    </ol>
    <p>For the third class of change, the Working Group <span class="rfc2119">MUST</span>
      either:</p>
    <ol>
      <li>Request that the Director issue a <a href="#cfr-edited">Call for
          Review of
          an Edited Recommendation</a>, or</li>
      <li>Issue a <a href="#cfr-corrections">Call for Review of Proposed
          Corrections</a> that have not been incorporated into an edited draft
        (e.g.,
        those listed on an errata page). After this review, the Director <span
          class="rfc2119">MAY</span>
        announce that the proposed corrections are normative.</li>
    </ol>
    <p>While the second approach is designed so that a Working Group can
      establish
      normative corrections quickly, it does not obviate the need to incorporate
      changes into an edited version of the Recommendation. In particular, when
      corrections are numerous or complex, integrating them into a single
      document is
      important for interoperability; readers might otherwise interpret the
      corrections differently.</p>
    <p>For the fourth class of change (new features), W3C <span class="rfc2119">MUST</span>
      follow the full process of <a href="#rec-advance">advancing a technical
        report to Recommendation</a>.</p>
    <h3>7.7 <a name="rec-rescind" id="rec-rescind">Rescinding a W3C

    <p>W3C <em class="rfc2119">may</em> rescind a Recommendation, for example
