> Is it really possible to make RDF useless with just changing
> the meaning of namespace URI
Certain parts of the RDF Model and Syntax rely on using properties as
attached to the end of namespaces. That is to say:
<Description xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#"/>
Refers to this RDF property:-
http://www.w3.org/1999/02/22-rdf-syntax-ns#Description
Of course, RDF parsers already understand that, but I could write a Schema
that is more explicit than that, and it would have to look it up.

Nah, because it wouldn't change. No-one is going to forbid anyone from
dereferencing a namespace (just as it is unwise to make it mandatory).

In a system x1, dereference the namespace accoroding to the specification
x2. In an RDF system, dereference the ns and parse it as an RDF Schema. How
is that not clear?

True (or more accurately: I agree). If I understand what you are saying
there...

It's fine saying that, but I can't debate it if there isn't a reason behind
that proposition :-) IOW: Why should no-one ever dereference ns'?
> PS. So *you* think URI points to RDF ?
Only in an RDF system. Well, even then it doesn't have to... there are some
"freak" cases that I have seen, like using mailboxes to define people.

Maybe, but what hassle!
