Kawa-XQuery provides an experimental extension allowing
the programmer to get servlet parameters, including the
request URL.  Some suitable (missing) helper functions
can hide the details and return a string you can pass
to 'document'. For more infomation, and an annotated example
see http://www.gnu.org/software/kawa/xquery/servlet.html

This is admittedly relatively rather low-level, and may
not be quite what you had in mind.  At the very least
you'd want a higher-level interface to hide the details
of the servlet API and URL parsing.
