One thing that comes to mind is that XML Query talks about "the namespace URI", while XMLNAMES uses the term "namespace name". Besides, a namespace name takes the form of a URI *reference*, not an URI. The other thing that is a bit strange is that because of the copy-rather-than-reference approach XML Query needs to define the semantics of XML namespace declarations *at all*. Julian
