As far as XQuery is concerned, I think this is good now, because XQuery 
uses the same data model as XSLT, and it's easy to infer the details 
from here. Thanks!

I'm not at all sure how GRDDL would expect a C or Javascript 
implementation to work, given the general framework, and I can't quite 
tell whether your text is trying to say that GRDDL supports any 
language, or that these other languages aren't really directly suitable 
so you don't try to offer support for them.  Saying one of these two 
things more clearly would be helpful.
