Still, the existance of other declarations Zeljko cited -- ><!ENTITY % NS.prefixed "IGNORE"> ><!ENTITY % XHTML.prefixed "%NS.prefixed;"> ><!ENTITY % XHTML.xmlns "http://www.w3.org/1999/xhtml"> ><!ENTITY % XHTML.prefix ""> ><!ENTITY % XHTML.xmlns.attrib "xmlns %URI.datatype; #FIXED >'%XHTML.xmlns; %XLINK.xmlns.attrib;"> suggests that a similar kind of surgery, albeit deeper, might suffice to get the DTD to suppress its hard-wired namespace declarations Unless something has gone wrong, that would require editing the DTD. It's supposed to be the DTD for XHTML and XHTML elements are in the XHTML namespace. You could edit the DTD to change the namespace name but that is just the same kind of edit as changing the local name of an element from say <h1> to <title> in either case the result is a DTD but its no longer XHTML. . Admittedly, it might be going a bit further than the designers intended. But the basic requirement of being able to use the same XSLT on documents with or without the DOCTYPE declaration, without a big song and dance in the stylesheet, seems quite reasonable to me. All that needs happen is that the source document follows th eadvice in both the namespace and XHTML documents and have an explicit xmlns="..." in the HTML element, then the document is XHTML whether or not the DTD is read.
