I agree that the protocol should override the query language in cases
where they both specify FROM and FROM NAMED elements, but don't agree
as to which they specify.

However, I can also live with our spec leaving this to implementations
(in which case I'd want to be able to communicate that policy in
SADDLE) or defining some kind of error message to return in case of
protocol & QL defining an "ambiguous RDF dataset".
