(I don't agree that the name is "arbitrary"; it's a matter of
convention, but that's not the same thing as arbitrariness, that is,
something that is (or should be) the result of chance, whim, or
caprice, lacking any substantive, reasonable, or rational
considerations. In this case, we obviously *do* have such
considerations: (1) not too long; (2) not too short; (3) not
misleading; (4) informative; (5) congruence...maybe others.)

Well, you say "overkill" and I say "unambiguous" -- honestly, I have
no idea what "data" means... And it's fine to name the parameter
"data", but as you pointed out, there's no named graph parameter to go
along with "data" yet; and once there is, "data" may not seem as good.

Anyway, as I pointed out, I'm pretty sure that in the actual bindings
in WSDL, the parameters can get new names; as things stand right now,
"default-graph-uri" and "named-graph-uri" are names of abstract
things. I believe we have a choice as to whether they also end up
being names of concrete binding parameters in HTTP.

Yes, I'm not proposing anything like that.

My real point is that I reach for my gun every time anyone says "the
names don't matter", since they obviously do.
