The Qexo implementation has a "write-to(DATA, URL)" function
to write extra output files.  I use this for the "picture
album" application I mentioned in the previous message:
All of the linked web pages are generated by a single
XQuery "run".  My XML.com article discuss the alternatives.

Of course write-to, in addition to being non-standard,
is awkward semantically because it is a side-effect in
an otherwise side-efefct-free language.  In practice,
that may not be a problem, but it would complicate any
attempt to formally define XQuery.  The same problem
is also likely for any attempt to add updates to XQuery.
