Fair enough.

I was thinking of something much more simple -- a simple parameter
marker (?) that allows you to pass in values a la SQL:

   FOR $book IN document("catalog.xml")//book
      WHERE $book/author = ?
   RETURN $book

Of course, if this isn't in the language, it's not possible. Then again,
it will be among the first non-standard extensions that people invent.
