I know we revised this table and the requirements in Minneapolis but this
thread was before that so...

Having a table that clearly say occurance counts, etc. is insufficient.
There are cases where "your best" is just not going to fly when doing
interop testing.  Other drafts/RFCs that have tables on stuff like this
(ie: HTTP Digest??  I dont have my drafts on my laptop) also clearly spell
out when a failure is fatal and when it is not.  The intent for this was to
avoid some intermediate server (ie: a hostile intermediate server) from
tampering w/the data stream and possibly getting private data, etc.

Just how should my CS proceed when there is no IRIPrev# line??  Assume
IRIPrev1?  Assume something else??  While IRIPrev1 and IRIPrev2 may be
legit in the same response to an iRIP v1 CS, it may be illegal in the real
iRIP v2 draft and the v2 server should be able to detect this and do the
proper thing (instead of punting!)

Ok, then tell vendors exactly how to do this.  You leave the entire concept
up to the imagination..  Are you _assuming_ IANA will just do this
automagically?  Are you assuming some other registration organization??
Dont leave this up to each vendors immagination; it is not a safe choice...
