Looks good to me.

XQuery is not yet fully integrated in the API. I did an intial attempt heavily 
inspired by the eXists implementaiton but there is no reference 
implementation yet and the whole thing needs some refinement before it is 
ready. I think we need to finalize how XQuery works with the API before 
extending your basic idea of referencing a' la xinclude to also include 
xquery. I see nothing bad with allowing xpath expressions as part of the URI 
though.
