<div style="margin-top: 1em; margin-left: 2em;">
The XML Core Working Group is a Working Group of the W3C and follows the
Working Group process described in section <a
href="http://www.w3.org/2004/02/Process-20040205/groups.html#GAGeneral">6.2
Working Groups and Interest Groups</a> of the <a
href="http://www.w3.org/Consortium/Process">Process Document</a>. <!--* Provisions
in this charter override the latter. *-->
 This is a modification of the charter for this Working Group. It extends and
supersedes the Working Group's <a
href="http://www.w3.org/2003/09/xmlap/xml-core-wg-charter.html">previous
charter of June 2004</a>. Except as specified in this charter, the Working
Group follows the <a
href="http://www.w3.org/2003/09/xmlap/xml-common-proc.html">Common Procedures
for XML Working Groups</a>.</div>

<div>
<h2>1. <a name="mission">Mission</a></h2>

<p>The mission of the <a href="http://www.w3.org/XML/Group/Core">XML Core
Working Group</a> is to maintain and develop as needed core XML
specifications.</p>
</div>

<div>
<h2>2. <a name="scope">Scope</a></h2>

<p>The XML Core Working Group is chartered to consider comments on the
following existing specifications:</p>
<ol>
  <li><a href="http://www.w3.org/TR/2004/REC-xml-20040204">XML 1.0</a>, <a
    href="http://www.w3.org/TR/2004/REC-xml11-20040204/">XML 1.1</a></li>
  <li><a href="http://www.w3.org/TR/1999/REC-xml-names-19990114">Namespaces
    in XML 1.0</a>, <a
    href="http://www.w3.org/TR/2004/REC-xml-names11-20040204">Namespaces in
    XML 1.1</a></li>
  <li><a href="http://www.w3.org/TR/2004/REC-xml-infoset-20040204">XML
    Information Set</a></li>
  <li><a href="http://www.w3.org/TR/2001/REC-xmlbase-20010627/">XML
  Base</a></li>
  <li><a
    href="http://www.w3.org/1999/06/REC-xml-stylesheet-19990629">Associating
    Stylesheets with XML</a></li>
  <li><a href="http://www.w3.org/TR/2001/REC-xml-c14n-20010315">Canonical
    XML</a></li>
  <li><a
    href="http://www.w3.org/TR/2002/REC-xml-exc-c14n-20020718/">Exclusive XML
    Canonicalization</a></li>
  <li><a href="http://www.w3.org/TR/2001/REC-xlink-20010627/">XML Linking
    Language</a></li>
  <li><a
  href="http://www.w3.org/TR/2004/REC-xinclude-20041220/">XInclude</a></li>
  <li>XPointer <a
    href="http://www.w3.org/TR/2003/REC-xptr-framework-20030325/">Framework</a>,
    <a href="http://www.w3.org/TR/2003/REC-xptr-xmlns-20030325/">xmlns()
    scheme</a>, <a
    href="http://www.w3.org/TR/2003/REC-xptr-element-20030325/">element()
    scheme</a></li>
</ol>

<p>The Working Group is responsible for:</p>
<ol>
  <li>updating errata documents and publishing new editions incorporating
    published errata when appropriate;</li>
  <li>maintaining the test suites associated with the specifications and
    providing careful updates as warranted.</li>
</ol>

<p>In addition to the maintenance effort, the XML Core Working Group will
react on the evolution of the XML Platform and could develop and extend the
core of the XML Platform when needed. Note that the development of new W3C
Recommendations, not listed in the deliverables section of this charter,
would require a new charter revision.</p>
</div>

<div>
<h2>3. <a name="deliverables">Deliverables</a></h2>

<p>This charter extends the ongoing work of the XML Core Working Group.</p>

<p>Since a sizable portion of this Working Group's work is ongoing in nature,
milestones and success consist of regular updates to Errata documents and
existing specifications. In addition to errata management, the Working Group
expects to:</p>
<ol>
  <li>Publish a second edition of the Namespaces in XML specification under
    the <a href="http://www.w3.org/TR/2002/NOTE-patent-practice-20020124">24
    January 2002 CPP</a> as amended by the <a
    href="http://www.w3.org/2004/02/05-pp-transition">W3C Patent Policy
    Transition Procedure</a>.</li>
  <li>Maintain conformance test suites for XML, and for other specifications
    where possible.</li>
</ol>

<p>The charter also includes the new W3C Recommendations:</p>
<dl>
  <dt><a href="http://www.w3.org/TR/xml-id/">xml:id Version 1.0</a></dt>
    <dd>People have expressed the need to define Id attributes in XML without
      requiring the use of a schema, be it a DTD, an XML Schema, or something
      similar. The XML Core Working Group has been tasked to address this
      request and will continue of the current W3C Candidate Recommendation
      for xml:id.</dd>
  <dt>XML Linking Language (XLink) Version 1.1</dt>
    <dd>A number of simple extensions to XLink 1.0 have been proposed. The
      XML Core Working Group published a <a
      href="http://www.w3.org/TR/xlink10-ext/">Working Group Note</a>
      describing specific possible changes and will produce XLink 1.1 to
      implement these changes.</dd>
  <dt>Canonical XML version 1.1</dt>
    <dd>The work on xml:id uncovered some inconsistencies in Canonical XML
      version 1.0 (see xml:id CR, Appendix C, "<a
      href="http://www.w3.org/TR/2005/CR-xml-id-20050208/#impact">Impacts on
      Other Standards</a>"). The Working Group will produce a new version of
      Canonical XML to address those inconsistencies, as well as others that
      might be discovered at a later stage.</dd>
</dl>
</div>

<div>
<h2>4. <a name="schedule">Schedule</a></h2>

<p>The XML Core Working Group has generally had strong liaisons with other
Working Groups, and it is appropriate for low-level infrastructure work to
proceed slowly and cautiously. This schedule is therefore to be taken as a
rough guide.</p>
<dl>
  <dt>April 2005</dt>
    <dd><ul>
        <li>xml:id moves to Proposed Recommendation</li>

</div>

<div>
<h2>5. <a name="duration">Duration</a></h2>

<p>The expiration date of this charter is 30 June 2006.</p>
</div>

<div>
<h2>6. <a name="relationships">Coordination With Other Groups</a></h2>

<h3>W3C Groups</h3>

<p>The XML Core Working Group co-chairs participates in the XML Coordination
Group to help track dependencies. In addition to all the Working Groups in
the XML Activity, the Internationalization Working Group is also expected to
provide last call review of deliverables of this Working Group.</p>

<h3>External Groups</h3>

<p>The XML Core Working Group needs to review and comment on work on the
definition of the Internet Media type for XML (see <a
href="http://www.ietf.org/rfc/rfc3023.txt">RFC 3023</a>).</p>
</div>

<div>
<h2>7. <a name="WGmembership">Working Group Participation</a></h2>

<p>Effective participation is expected to consume one workday per week for
each Working Group participant (though closer to a third of a day per week
average for the W3C Team Contacts); two days per week for editors.
Participants must continue to fulfill the <a
href="http://www.w3.org/2004/02/Process-20040205/groups.html#group-participation">participation
requirements</a>.</p>

<p>To be successful, we expect the XML Core Working Group to have 10 or more
active participants for its duration.</p>

<h3>Chair</h3>

<p>The initial chairs of this Working Group are Paul Grosso, Arbortext and
Norman Walsh, Sun Microsystems.</p>

<h3><a name="W3CResources">W3C Team Contact</a></h3>

<p>The initial W3C Team contacts are Henry Thompson and Philippe Le Hégaret.
It is expected that this Working Group would consume about 0.15 FTE of Team
resources, including administrative logistics.</p>
</div>

<div>
<h2>8. <a name="meetings">Meetings</a></h2>

<p>The Working Group uses a public mailing list for technical communication
<a
href="http://lists.w3.org/Archives/Public/public-xml-core-wg/">public-xml-core-wg@w3.org</a>,
supplemented by teleconferences approximately once per week. The yearly W3C
Technical Plenary meeting is expected to fulfill the need for face-to-face
meetings.</p>
</div>

<div>
<h2>9. <a name="communication">Communication</a></h2>

<p>The XML Core Working Group shall communicate among its participants using
the public mailing list <code><a
href="http://lists.w3.org/Archives/Public/public-xml-core-wg/">public-xml-core-wg</a></code>.</p>
</div>

<div>
<h2>10. <a name="Confident">Confidentiality</a></h2>

<p>The proceedings of this Working Group are public, with exceptions made by
the co-chairs with the Working Group's agreement.</p>
</div>

<div>
<h2>11. <a name="IP">Patent Policy</a></h2>

<p>This Working Group operates under the <a
href="http://www.w3.org/Consortium/Patent-Policy-20040205/">W3C Patent
Policy</a> (5 February 2004 Version). To promote the widest adoption of Web
standards, W3C seeks to issue Recommendations that can be implemented,
according to this policy, on a Royalty-Free basis.</p>
