Well, you can set the default namespace *within* the DTD, which may be resolved from the PUBLIC id. I just got caught with this using XPath in XSLT, when I was matching on some html. It worked as long as the DOCTYPE was not defined. This is because the the XHTML DTD (which was found via the SYSTEM url) defines a default namespace, as if you'd done <html xmlns="http://foo..."> in the source html document. XPath in XSLT without a namespace qualifier won't match the default namespace, so you have to locate the DTD, do a search for "xmlns" in it, define that namespace in your XSLT and then use the namespace in your XPath. I'm sure you all know this, but I just thought I'd provide it as another possible example of the problems with default namespaces. -- Mike
