But it would also be one that would simply quit working when the
network connection went down. As someone else suggested: you're
assuming web applications and XML and URIs get used in awfully
unconnected places.

Yes. The IETF has made very specific decisions not to turn the IANA's
web resources into a directly downloadable schema repository. That's
why we created the 'ietf' URN namespace and are putting permanent
references to IANA registry entries there instead of making 'iana.org'
follow the w3.org example. We _don't_ want things failing becuase
the IANA decided to re-arrange its website. That's called a single
point of failure and its _not_ what the Internet is supposed to have.

Thanks. I'll tell the MPEG and ISBN associations that you think they're 
nefarious or incomptent....

So far the TAG's cognitive process isn't giving me warm fuzzies about
its output....
