XML Query is not yet a Recommendation. As of this week the
specifications are for the most part in Last Call Working Draft.
Implementations are often one or more drafts behind - this is most
noticeable in the syntax of type construction and function
declarations, and in the treatment of empty sequences,
or that's what I've noticed so far.

Can you give a simple example? I've used doc() more than once
in the same query with Lucents Galax, for example (obviously
giving a different URI each time for it to be useful).

Since XQuery 1.0 doesn't exist yet, there are no tools :-)
However, there are approximately two dozen implementations in
various stages of completeness listed on the public XQuery Web
page at http://www.w3.org/XML/Query that you can investigate.
