An address. Is "c:\gtn\mydoc.html" a query against "gtn"?
To me an address returns a resource (a deterministic
result), while a query does not necessarily return

It makes equally as much sense to say that an Xptr points to
a resource (as you note yourself) and to not have a distinction.
XML even allows arbitrary well-formed sub-trees to be parsed
outside of the context of the containers above it, lending even
stronger weight to the idea that any resource (by your definition)
is addressable by itself. The fact that groves codify the object
structure also adds weight.

Well, let's agree to differ, because I have a least as much
experience in the WWW as you, and the software that I am responsible
for works perfectly well with parameters, thank you very much.

Bollocks. I question the need for any "new-to-the-web" semantic,
because we've had sub-document addressing for more than 2 years.
If a URL is an address for a resource (something that is
addressable), what more do you need? Why do you need to create
some artificial distinction between a resource and a sub-resource,
which by your definition, are the same thing (something
addressable)? All you are really doing is reinventing something
like my proposal of long ago with a different syntax and hairy

No. An RFC is an RFC. It is not a standard. It is not even normative.
RFC's codify existing practise or ideas. Running code wins in the
IETF, and we've had running code for over 2 years.
I agree with Lee. We need client-side fragment specs, but nothing
else. Everything else is an address into the address space
of the server, and it controls the format and interpretation of
them. I find parameters much cleaner, and will use them.
