But I asked the question: Shouldn't transformation only happen if the 
de-referenced resource isn't RDF? Why would you transform RDF to RDF?

But you aren't responding to my point. What do you mean by RDF in this 
transformation context? Not for me, but for readers of the spec, to be 
crystal clear.

Again, you change my comments. I said:  A lookup occurs against the 
resolved RDF graph.

Queried is a little loaded. Not inaccurate, since you achieve a lookup 
via a query, but it is loaded all the same. Again, not for me, but for 
spec readers.

Yes, and my fundamental point is more about loosely associating SPARQL 
with WebID. It's an implementation detail. Of course, if you "query" 
usage is in the context of the SPARQL ASK section of the spec, then 
fine, context is established for the spec reader.
