<h3 id="docconf"><span class="secno">2.1 </span>Document Conformance</h3>

<p>A strictly conforming XHTML+RDFa document is a document that
requires only the facilities described as mandatory in this
specification. Such a document satisfies the following
criteria:</p>

<ol>
    <li>
<p>The document <em title="must" class="rfc2119">must</em> conform to the constraints expressed in the schemas in
<a href="#a_xhtmlrdfa_schema">Appendix&nbsp;A -
XHTML+RDFa XML Schema</a> and
<a href="#a_xhtmlrdfa_dtd">Appendix&nbsp;B - XHTML+RDFa
    Document Type Definition</a>.</p>
</li>

<li>
<p>The local part of the root element of the document <em title="must" class="rfc2119">must</em> be
<code>html</code>.</p>
</li>

<li>
<p>The start tag of the root element of the document <em title="must" class="rfc2119">must</em> explicitly
contain a default namespace declaration for the XHTML namespace
[<a href="#bib-XML-NAMES11" rel="biblioentry" class="bibref">XML-NAMES11</a>].
The namespace URI for XHTML is defined to be 
<code>http://www.w3.org/1999/xhtml</code>.</p>

<p>The start tag <em title="may" class="rfc2119">may</em> also contain the
declaration of the 
XML Schema Instance Namespace and an XML Schema Instance
<code>schemaLocation</code> attribute [<a href="#bib-XMLSCHEMA-2" rel="biblioentry" class="bibref">XMLSCHEMA-2</a>]. Such
an attribute would associate the XHTML namespace
<code>http://www.w3.org/1999/xhtml</code> with the XML Schema at the
URI <code>http://www.w3.org/MarkUp/SCHEMA/xhtml-rdfa-2.xsd</code>.</p>

<pre class="example" title="Sample root element">&lt;html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.w3.org/1999/xhtml
                          http://www.w3.org/MarkUp/SCHEMA/xhtml-rdfa-2.xsd"
&gt;</pre>
</li>

<li>There <em title="should" class="rfc2119">should</em> be a <span class="aref">@version</span> attribute on the 
<code>html</code> element with the value 
"<code>XHTML+RDFa 1.1</code>".</li>

</ol>

<pre class="example" title="Example of an XHTML+RDFa 1.1 document">&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;<span class="hilite">html</span> <span class="hilite">xmlns="http://www.w3.org/1999/xhtml"</span> 
    <span class="hilite">version="XHTML+RDFa 1.1"</span>
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.w3.org/1999/xhtml
                        http://www.w3.org/MarkUp/SCHEMA/xhtml-rdfa-2.xsd"
    lang="en"
    xml:lang="en"&gt;
  &lt;head&gt;
    &lt;title&gt;Virtual Library&lt;/title&gt;

    &lt;p&gt;Moved to &lt;a href="http://example.org/"&gt;example.org&lt;/a&gt;.&lt;/p&gt;
  &lt;/body&gt;
&lt;/html&gt;</pre>

<p>Note that in this example, the XML declaration is included. An XML
declaration like the one above is
not required in all XML documents. XHTML document authors
<em title="should" class="rfc2119">should</em> use XML declarations in all their documents.
XHTML document authors <em title="must" class="rfc2119">must</em> use an XML declaration
when the character encoding of the document is other than the default UTF-8 or
UTF-16 and
no encoding is specified by a higher-level protocol.
</p>

<p>XHTML+RDFa documents <em title="should" class="rfc2119">should</em> be labeled with the Internet Media Type "application/xhtml+xml" as defined in [<a href="#bib-RFC3236" rel="biblioentry" class="bibref">RFC3236</a>].  For further information on using media types with XHTML family markup languages, see the informative note [<a href="#bib-XHTML-MEDIA-TYPES" rel="biblioentry" class="bibref">XHTML-MEDIA-TYPES</a>].

<div class="section" id="user-agent-conformance">
<h3 id="uaconf"><span class="secno">2.2 </span>User Agent Conformance</h3>

<p>A conforming user agent <em title="must" class="rfc2119">must</em> support all of the features required

<li>The <a title="current_language" class="tref">current language</a> can be set using either the
<span class="aref">@lang</span> or <span class="aref">@xml:lang</span> attributes.  </li>
<li>In section 6.5, processing step 6, if no URI is provided by a resource attribute, then
first check to see if the element is the <code>head</code> or
			  <code>body</code> element. If it is, then act as if there is an empty <span class="aref">@about</span> present,
                and process it according to the rule for <span class="aref">@about</span>.</li>
<li>In section 6.5, processing step 7, if no URI is provided, then 
first check to see if the element is the <code>head</code> or

<p>The terms defined in this section <em title="must" class="rfc2119">must</em> be mapped to 
lower case by an RDFa Processor.  The vocabulary terms are:</p>

<dl>
<dt>alternate</dt>

<dd>Designates alternate versions for a resource.</dd>

<dt>appendix</dt>

<dd>Refers to a resource serving as an appendix in a collection.</dd>

<dt>bookmark</dt>

<dd>Refers to a bookmark. A bookmark is a link to a key entry point within an
extended document. The 
<span class="aref">@title</span> attribute may be used, for example, to
label the bookmark. Note that several bookmarks may be defined for a
document.</dd>

<dt>cite</dt>
<dd>
<p>Refers to a resource that defines a citation. 
In the following example, the <code>cite</code> is used to
reference the book from which the quotation is taken:</p>

<pre class="example" title="cite as book reference">As Gandalf the White said in 
&lt;span <span class="hilite">rel="cite"</span> resource="http://www.example.com/books/the_two_towers"&gt;
    The Two Towers
&lt;/span&gt;,
&lt;quote xml:lang="en"&gt;"The hospitality of 
your hall is somewhat lessened of late, Theoden King."&lt;/quote&gt;</pre>
<p>which would generate the following triples:</p>
<pre class="example">&lt;&gt; xhv:cite &lt;http://www.example.com/books/the_two_towers&gt; .</pre>

<code>cite</code> is also useful for referencing specifications:
<pre class="example" title="cite to reference another specification">More information can be found in

<p>This appendix is <em>normative</em>.</p>

<p>This appendix includes an implementation of the 
XHTML+RDFa 1.1 language using XML Schema. 
It is implemented by combining the XHTML 1.1 Schema
with the XHTML Metainformation Attribute Module.
This is done by using
a content model module, and then a driver module.
There are direct links to the various files, and the files
are also contained in the "Gzip'd TAR" and "Zip" archives linked to at the

            XHTML Document Model 
            This module describes the groupings of elements/attributes 
            that make up common content models for XHTML elements. 
            XHTML has following basic content models: 
               xhtml.Inline.mix; character-level elements
               xhtml.Block.mix; block-like elements, e.g., paragraphs and lists
               xhtml.Flow.mix; any block or inline elements 
               xhtml.HeadOpts.mix; Head Elements 
               xhtml.InlinePre.mix; Special class for pre content model 
               xhtml.InlineNoAnchor.mix; Content model for Anchor 
            
            Any groups declared in this module may be used to create 
            element content models, but the above are considered 'global' 
            (insofar as that term applies here). XHTML has the
            following Attribute Groups 
               xhtml.Core.extra.attrib 
               xhtml.I18n.extra.attrib
               xhtml.Common.extra 
            
            The above attribute Groups are considered Global 
        &lt;/xs:documentation&gt;

    Note however that it is not possible to add

    modification. To add RDF metadata to the head
    of a document, modify the structure module.

<p>This appendix includes an implementation of the 
XHTML+RDFa 1.1 language as an XML DTD. 
It is implemented by combining the XHTML 1.1 DTD
with the XHTML Metainformation Attribute Module.
This is done by using
a content model module, and then a driver module.
There are direct links to the various files, and the files
are also contained in the "Gzip'd TAR" and "Zip" archives linked to at the

&lt;!-- XHTML+RDFa Document Model

     This module describes the groupings of elements that make up
     common content models for XHTML elements.

     XHTML has three basic content models:

         %Inline.mix;  character-level elements
         %Block.mix;   block-like elements, eg., paragraphs and lists
         %Flow.mix;    any block or inline elements

     Any parameter entities declared in this module may be used
     to create element content models, but the above three are
     considered 'global' (insofar as that term applies here).

     The reserved word '#PCDATA' (indicating a text string) is now
     included explicitly with each element declaration that is
     declared as mixed content, as XML requires that this token
     occur first in a content model specification.
--&gt;
&lt;!-- Extending the Model

     While in some cases this module may need to be rewritten to
     accommodate changes to the document model, minor extensions
     may be accomplished by redeclaring any of the three *.extra;
     parameter entities to contain extension element types as follows:

         %Misc.extra;    whose parent may be any block or
                         inline element.

         %Inline.extra;  whose parent may be any inline element.

         %Block.extra;   whose parent may be any block element.

     If used, these parameter entities must be an OR-separated
     list beginning with an OR separator ("|"), eg., "| a | b | c"

     All block and inline *.class parameter entities not part
     of the *struct.class classes begin with "| " to allow for
     exclusion from mixes.

<p>Documents written using the markup language defined in
this specification can be validated using the 
DTD defined in <a href="#a_xhtmlrdfa_dtd">Appendix A</a>.  If a document author wants
to facilitate such validation, they may include the following 
declaration at the top of their document:</p>

XHTML Family of markup languages uses the
mechanism for transforming XHTML+RDFa documents into
RDF as defined by [<a href="#bib-GRDDL" rel="biblioentry" class="bibref">GRDDL</a>].
Authors who want to be certain their documents are
transformable by all [<a href="#bib-GRDDL" rel="biblioentry" class="bibref">GRDDL</a>] processors may
also include a <code>profile</code> attribute on the 
<code>head</code> element that includes a
reference to the XHTML vocabulary URI
<code>http://www.w3.org/1999/xhtml/vocab</code>.</p>
