A generic resolution procedure might talk about what to try first,
what to use as a fallback, how errors should be reported, how
access controls might work, etc.

No, what I meant by a generic URC syntax was how we should set up
the general scheme for people to create custom URCs. There are lots
of different sorts of info that people will want to jam into URCs
to build their special applications. How do we let them do so
while still providing a reasonable measure of interoperability?

This was the big impetus behind the SGML URC draft put out by
Terry Allen and myself. According to that spec, URCs do not have
to be sent in text/sgml (although they can). Instead, novel URCs
have a SGML DTD to define their elements.

If these syntaxes are to be standardized, who else should do it?
