Thanks for a (generally) great document Michael,

As a process, I suggest keeping this document intact, but progressing
several smaller documents as the RFCs - Specifically I'd suggest
excluding the description of specific tags/values from the first copy of
the document so that we can agree on encoding first. I'd also suggest
making hte whois++ stuff a seperate document, and throwing out section
4.1 (future stuff) entirely :-)

The only comment on the encoding is to strongly support the Precedences
idea. (Since I think I was the one to propose it, this should suprise
noone :-) It keeps things simple for simple URC's. I'd like to see a way
of specifying complex precedence while recognising that in most URCs it
wont be required - something like Braces would be a simple way of doing
this, and most URC maintainers (the non computer-science literate example
of MM's paper) would never see them.

I'd also like to see us support multi-valued values, Author is the
obvious example of this.

Now - on the non encoding side of the document.

Author should include the email address, as in the "From:" field of
RFC822, e.g.
Author: Mitra <mitra@path.net>

TTL is lousy - it makes a URC dependant on the time it was created,
Expires is a much better way of doing this, specify the specific time to
throw it out. I also fail to understand the problem people are hving
with understanding what it applies to, since this is covered by the
precedence rules (I think - but maybe I'm missing something).

Thanks again Michael.
