Additional MIME type review

Reminder for those of you who are at IETF: In addition to the two
scheduled content subtype review sessions, there are other efforts going
on that should get careful review by the MIME community.  

In particular, the WG that is working on PEM and its relationship with
MIME is meeting Wednesday at 1330.  Since this work is critical to uses of
email and MIME that require authentication and interacts strongly with
other uses of MIME, I'd strongly encourage people to follow and
participate in the decisions being made there.
