It was simply that in the XQuery WD there's no mention of parameters in the query prolog. Perhaps they're waiting in the wings. I guess that you could have parameterisation through separate XML documents accessed by document() (though without being able to supply the location of the document as a parameter, you're pretty limited). Maybe you'd have queries that consisted purely of function definitions, which are then included into other queries, and called with specific arguments (err... actually, I can't see a facility for combining separate queries, so I guess that wouldn't work, unless perhaps XQuery uses XInclude for this).
