Template rules are just syntactic sugar for a recursive function call and a case statement, both of which XQuery has (doesn't it?). I would be inclined to nominate some of the axes (almost everything but children and descendants) as the prime things to exclude from XQuery, both because they are hard to optimize and hard to statically type in any sort of useful way.
