open-in-new
<h2 id="method">Method</h2> <p>XHTML Modularization consists of three essential parts </p> <ol><li>a technique or methodology (as explained, actually independent of XHTML, and applicable to any XML-based markup language) for defining abstract modules of a markup language, and implementing those modules in various schema languages, such as <a href="/facts/Document_Type_Definition/JsvY9PyQ">DTDs</a>, <a href="/facts/XML_Schema_(W3C)/X6Uly3dm">XML Schema</a>, and <a href="/facts/Relax_NG/16dj0TGq">Relax NG</a>.</li> <li>a collection of abstract modules</li> <li>a number of implementations of those modules in various schema languages.</li></ol> <p>To define a language using these modules, you only have to define a <i>driver</i> in one or more of the implementation schema languages, that causes the necessary modules to be loaded. </p> <h2 id="application-to-xhtml">Application to XHTML</h2> <p>In its application to XHTML, it provides a means for defining modules of <a href="/facts/XHTML/6qHnmJSg">XHTML</a> to allow subsetting and extending XHTML in a controlled way.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p><p>Core modules are: </p> <ul><li>Structure (html, head, body, title...)</li> <li>Text (h1, h2, h3... p, pre...)</li> <li>Hypertext (a)</li> <li>List (ul, li...)</li></ul> <p>Other modules include applet, image, forms and basic forms. </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"Modularization of XHTML - W3 Consortium". <a href="http://www.w3.org/TR/xhtml-modularization/" target="_blank">http://www.w3.org/TR/xhtml-modularization/</a> <a href="#fnref:1" class="footnote-back-ref">↩</a></p></li> <li id="fn:2"><p>"Modularization of XHTML in Relax NG". <a href="http://www.thaiopensource.com/relaxng/xhtml/" target="_blank">http://www.thaiopensource.com/relaxng/xhtml/</a> <a href="#fnref:2" class="footnote-back-ref">↩</a></p></li> </ol>
