But because all elements and attributes are namespaced in XML and the W3C jealously guard their XHTML namespace from extension by others, a site author may not do the same with XHTML-based markup. While it is certainly possible to build a custom XML DTD to include an <code>autocomplete</code>, the act would be meaningless as the W3C have made it clear they would not regard documents extending the XHTML namespace in this way as even using XHTML at all ([http://www.w3.org/TR/xhtml-modularization/conformance.html#s_conform XHTML Modularization 1.1: Working Draft: Conformance Definition], also see [http://alistapart.com/articles/customdtds2/ A List Apart: More About Custom DTDs]). | 4.
