This definition of query sounds more like a query string. SPARQL
queries have semantics and results. Success/failure seems implicit
in that.

If someone writes a SPARQL Query over SMTP protocol, they MUST
create tell the requestor if the query succeeded. SPARQL Protocol
uses the SPARQL Query Results Format but I don't expect all APIs
and protocols will. I think success/failure is a reasonable low
bar for conformance.

I'd much prefer that this conformance section be relevent to folks
developing APIs (which I expect to be numerous) and protocols (which
will probably be less numerous).
