Just to be complete even though you said you were joking, I just rechecked using my copy of IE5. The XML with DTD works even though there is no namespace attribute declared in the DTD. My exact version of IE5 is 5.00.2614.3500, 128 bit update versions q231452, q231450 The actual xml document I tested is the following, based on Anand Raman's original mailing: ========================================================================= DOCTYPE experience[ <!ELEMENT experience (project+)> <!ELEMENT project (title,employer?,client?,duration?,team?,position?,description?,contribution ?)> ]> <experience xmlns:exp="http://www.angelfire.com/ar/diduknow/experience"> <project> <exp:title>Management Information Systems</exp:title> <employer>Infotech ESD</employer> <client>Finance Department</client> <exp:duration>till date</exp:duration> </project> </experience> ========================================================================== When I say that "it works", I mean that IE5 displays the document text and does not give any error messages. > If you convert HTML to nice neat XHTML and then try to use a reference > to the DTDs supplied by W3C you get errors.

No-one has explained why, and there is little justification for The W3C namespace recommendation does say that if you use a DTD you have to declare the namespace. It also says that the namespace declaration can be established by the default value for the (namespace) attribute. This implies that you may optionally declare its value in the DTD (#FIXED would also be optional), and then you would not have to specify the namespace when you actually write an element. But my version of IE5 insists on needing the namespace declaration in the element event if the DTD declares it as #FIXED! Also, the Recommendation says that element and attribute name declared in the DTD must be qualified. Again, my copy of IE5 differs, since it would not allow the qualification in the DTD. Christopher R. Maden is right when he said that the above example for IE5 would not validate against the Recommendations, but it does work with my IE5. So I don't bother using IE5's xml or xsl capabilities. It's not worth it even for use as a learning tool, you have to unlearn too much. > it, so the only solution is to remove the DTD reference - and of course > you no longer technically have valid XHTML!!!!!! > > Damn.
