Well, I had planned to just stop after that note, on the theory
that the IESG should now have enough information to make
whatever decision they are inclined to make.   My personal
recommendation, I trust obviously, is that they should say "no"
to this particular draft as a proposed standard: for
standardization purposes, it just isn't specific enough about
what is being transmitted.

If I were giving advice to the author, it would pretty closely
follow what I understand Keith to be suggesting.   Withdraw this
document and the request that it be considered for PS.  Generate
a new document that is very specific about how much or how
little can be assumed when something arrives with this content
type, makes it explicit that the receiver had better be prepared
to handle any of the various mbox forms, and points to whatever
documentation or other materials that can be easily identified
and might help in constructing a receiver-processor.   I think
that document should be Informational, with a media type in some
non-IETF tree, but could personally live with a Proposed
Standard if the interoperability constraints, and any security
risks from guessing wrong about properties of the format were
extremely explicit.

Does that agree with your analysis, at least to a first order
approximation?

    john
