Hi Jim,

It's been a while - I remember corresponding with you back in the XQL days. 
I *think* that XQuery should handle this requirement for you. You can write 
a query, then apply it to a collection of documents, and the collection 
does not need to be stated anywhere in the query. So if the protocol sets 
up an environment in which a query should be executed, it should work.

I may be missing out on some of the details, though.

CAVEAT EMPTOR

Read the spec carefully, and let us know any problems you find.

Jonathan
