No I only agreed with the last part (not conflating names with things)
I admit that that wasn't at all clear in the way I quoted it (although
it may have been clear from the rest of my message that I didn't agree
that the namespace is the resource)

Yes but using "identify" in that way makes it appear confusing as only
one of those 2 is identification in the sense of UR_I_.
The URI RFCs specify a mapping from strings (called URI references) to resources.
The Namespace Rec specifies a mapping from the same strings to namespaces.

(Given that one can say just about anything is a resource then one can
also say a namespace is a resource, but even if you do that the
second mapping is in principle a different mapping)

Both mappings are restricted to strings that obey the lexical
constraints on URI references. But they are different mappings.

identifies (I think) the same resource as 
as empty fragment identifiers are explictly mentioned in the URI specs
as refering to the base.
But the Namespace spec goes to some lengths to stress that the
namespaces named by these two strings are different.

You see the quoted "bottom line" has no weight

then it says it is the XSLT namespace.



then it says the same thing.

The first one is right and the second one is wrong (try writing an XSLT
stylesheet with that namespace) I know which is right from reading the
XSLT REC, and that's the only way.
What I get back from dereferencing the namespace name as a URI
may be a hint as to what the namespace is about but it can, as
demonstrated, be wrong.
