I've updated my "test harness" (cobbled together collection of Ant tasks 
and various other bits) to handle the new manifest setup for the syntax 
tests and to handle both positive and negative syntax tests. With these 
updates, my engine passes all* of the syntax tests (positive and 

It also passes all four of the triple-match tests.

Looks like a good start to me.


* Actually, my engine right now does function resolution while parsing, 
and so fails a few tests which include functions in ORDER BY conditions or 
FILTERs (but doesn't fail with parse errors). The queries themselves parse 
just fine -- my code is just being a bit overeager. So I counted them as
