I don't see a dichotomy there. For every programming environment in
existance, we need a single implementation of an "XSL pattern parser."
This tool builds a grove from the XSL pattern and makes it available to
XML developers. Would you say that every developer who uses MPEG in his or
her program writes an MPEG decoder?

#1. I'm not convinced that the current proposal makes complex things hard.
#2. If the concept of a query is going to be generalized beyond XSL (which
it inevitably will have to be) then being parallel to the generation
syntax is not a benefit.

Even if it is not generalized, being parallel could also be confusing.
Let's please remember the lesson of the overwhelming popularity of
languages in the LISP family. People don't like so much consistency.
"Consistent inconsistency" is easier to scan visually.
