Hmm... OK, if there are some process rules that we believe
will result in more persistent, reliable names, then it's
worth writing them down.

I think it's a contractual issue, and not worth specifying in
a technical sense. But that's just my intuition, and in the
case of process, the relevant question is whether the participants
of the IETF are willing to standardize some contractual
properites. It seems that you/they/we are, so away we go...

But it seems perfectly feasible, to me, for the connection
between a URI and this URN process contract to be
outside the identifier itself. That is, rather than


which syntactically binds the name to the URN process contract,
it seems sufficient to write


and have the ISBN scheme specification say "this scheme
conforms to the URN process contract."

If not, please somebody explain why not, and write it
up in a spec, and let's review it.
