Hi Tim,

I think we're (and Larry) talking at cross-purposes here.

Not at all.  Depending upon one's opinion of httpRange-14 (which I'm
not trying to reopen!), either http URIs identify "network accessible
resources", or they identify "anything.  Either way, what I'm talking
about is *which* "network accessible resource" or "thing" a particular
URI identifies.  Neither IANA, RFC 2396, nor RFC 2616 sec 3.2.2 have
anything to say about that.

The line in the Arch doc that triggered this thread was;

  "The authority over a URI determines which resource it identifies."

And I assumed it was talking about the authority part of the URI, not
