I always felt that XSLT was intended to be purely functional, a language 
without side effects - I don't remember seeing a defined operational 
semantics (saying what order actions are taken in), just denotational (saying 
where information is taken from and what is done to it) :-)

Putting POST capability into XSLT would break this, since (depending on the 
XSLT engine in use) a document-post(url) might cause zero, one, or any number 
of actual POSTs unless that function alone had a partial operational 
semantics defined... which would be a bit hairy.
