It may be just that I'm in camp (1), but I think the spec falls apart if you treat the namespace URI as anything other than a magic cookie. That is, this namespace is the same as that namespace iff their URIs are identical. The files at two different URIs may be the same, but that does not make the namespaces identical; the same URI may return a randomly selected collection of Keats's works to each request, but two namespaces using it are the same URI. In XSL, a pattern matches an element if the URI of the pattern's element's namespace in the stylesheet matches the URI of the element's namespace in the document, and if the rest of the element type matches exactly. This allows styling of documents with namespaces; processing with special-purpose applets could be handled similarly. No further comparison can meaningfully be made in any reliable way; it requires further definition from the WG, which may well not be forthcoming. -Chris -- <!NOTATION SGML.Geek PUBLIC "-//Anonymous//NOTATION SGML Geek//EN"> <!ENTITY crism PUBLIC "-//O'Reilly//NONSGML Christopher R.
