Makes sense. Two issues, one technical, the other process.
The technical issue: Critical Content defaulted to (in RFC 3204 terms)
"optional". RFC 3204's default handling is "required".
The process issue: How is the average standards person to guess in a million
years that a draft on ISUP signaling is where to look for a MIME message
handling function? Why was this not a separate draft? It's not a problem
for me to write it up (although I may not make it by Friday). However, I'm
hesitant to "break" RFC 3204 by stating that the sense of the default
handling changes. That said, saying that RFC 3204 is correct will break
EVERY MUA. I would offer that it's a whole lot easier to change the four
SIP UA's that understand this parameter (i.e., change RFC 3204) than it is
to change the millions of MUA's out there. You may recall that we started
down the "assume required" path and very quickly decided that it was
untenable.

Subject: [VPIM] IESG review of draft-ietf-vpim-cc-04.txt
IESG discussion of this proposal turned up something I should have caught
myself: There's already a content-disposition parameter defined for
this purpose! See RFC 3204 for details of the "handling" disposition
parameter.
I hope it is obvious that having two parameters that do the same
thing is a bad idea. Accordingly, I suggest that this proposal be recast
as an informational document describing how to use the handling
parameter in the context of email.
One thing does appear to be missing from RFC 3204: Discussion of what
this parameter's default is. I think this is an important point, so an
additional document really is needed here.
