Not according to any definition of "deferencing" that I know about,
which is to retrieve a data representation of a resource. Perhaps
"accessing" is a better word.

At any rate, this is a minor point.

Of course.

Did you even read this citation? It says that URNs were designed with
the same goals in mind, but that URLs may be suitable as well. It does
*not* say only to use URNs! Is there some weird confusion about this?
There is no specification in the world that I am aware of that stops
you from using URLs as namespace names. There are hundreds of XML
related technologies that use URLs as their namespace names. They all
work just fine. That is the only acknowldgement I want at this stage -
that URLs as namespaces *work*, even if they aren't ideal for all

The world isn't going to listen unless you are both reasonable and
realistic in your statements. Trying to get a world of highly
conservative (small "c") technologists to take up some weird new
suggestion when their current methods work just fine isn't going to
fly unless you understand that you're fighting against the tides, as
it were.

Yes, URNs or some other kind of URI scheme for generic identification
of arbitrary concepts is a good idea, and it is easy to deploy and so
forth. But if you start inferring plainly rediculous things such as
"URLs as namespaces should be banned", then people are just not going
to listen. You want to give them the choice - forcing people to do
anything that they don't *need* to do, especially without due reason,
is just going to alienate them, and run contrary to your cause.

You have some good ideas, but I think you need to sit down and think
carefully about how you're going to publicize them.
