To quote Mike Kay's post in xml-dev comparing the corresponding XSLT and XQuery code for an identity transformation http://lists.xml.org/archives/xml-dev/200412/msg00129.html "But in fact there's a bigger issue - the XQuery code is wrong. It loses the namespaces from the source document. Perhaps I'm missing something, but I can't see any way to solve this. XQuery may be computationally complete, but it's not actually closed over the data model - there is no way of generating a namespace dynamically. As far as I can see at the moment, that's a stopper, and this exercise has to be coded in XSLT. Of course, I'm sure there are other problems where XQuery has the edge." Cheers, Dimitre Novatchev
