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*.
