Surely what you really want is an XSLT processor in the XML database? 
There's no reason why you need XQuery to access an XML database if it 
will let you send it XSLT directly, and return you the results.

Right - that would be the other way to do it. If you want your XSLT to 
be executed by the database client, you can just make calls into the XML 
database from the XSLT. This approach would give less scope for the 
database to optimise the XSLT using it's indexes though.
