They're fine; thinking about this, I was meandering off into quads
ot context URIs, or some other extension...

Otherwise tho'  being able to make statements about a graph is a 
major use-case atm for me. But there  doesn't seem to be any legal 
while sane way to do this - reflection/reification is not how I want 
to go about it, even if I was sure the semantics would pan out 
(reification to identify a graph?).
