Probably so. I'm having trouble understanding the XHTML conformance requirements myself: can't make sense of modularization conformance section Dan Connolly (Thu, Jul 06 2000) http://lists.w3.org/Archives/Public/www-html-editor/2000JulSep/0012.html "validate against"??? Dan Connolly (Thu, Feb 10 2000) http://lists.w3.org/Archives/Public/www-html-editor/2000JanMar/0100.html In any case, if I were an implementor, I would key off the presence of an xmlns attribute in the first start tag to detect XHTML. i.e. if the string "xmlns" occurs beteween the first "<html" and the first ">" that follows it then treat it as XHTML. Hmm... it might be nice to support other prefixes for the XHTML namespace, so you might use "<" followed by an XML name to find the first start tag. > [1] http://www.w3.org/TR/xhtml1/#uaconf > [2] http://www.ics.uci.edu/pub/ietf/http/rfc2616.txt > > L.
