Sometimes but also sometimes not. http-range-14 says that when the 
response code is 200, the answer is yes. As I say, I don't like this 
much either; but I can't see any feasible other way to answer the 
question at all for a given URI.

I take it that your answer would also be: maybe, maybe not; but that 
you would want the decision to depend not on an http code, but 
instead on some RDF assertions which would be accessible from the URI 
(in a way I confess to not following yet, but ...) Is that right?
