One other issue that I was thinking of - is the contents of the
Content-ID: field supposed to be globally unique, or just unique
within the message? I would assume that each Content-ID: should be
globally unique like the Message-ID: is. I ask because I'm thinking
about how one body part would reference another, and how this
interacts with digests of messages which might also have Content-ID:
headers imbedded in them.
This was also my assumption.
