I think we reached consensus on this issue at the last IETF, but I would
like to check in with everyone, to see if I'm correct on this.

The debate is over the situation of a document which is available in
multiple variants (e.g. Postscript, text, Giff etc). The question
was whether:

a) we assign a single URN to this (and pass it around with
attribute information to distinguish the variant to choose) or

b) assign a URN to each of the variants, with the attribute information
telling us about the document we have.

I believe we consensed on (a) because it allows us to present users with
a choice of variants. If this is not the case, then we need a decision soon
because it fundamentally affects the design of information systems using
URN's.

Chris - If there isnt consensus on this, then can you put it on the agenda
for Houston.
