This would mean that the key holder can handle both PGP/MIME and
partitioned formats, but that he prefers to receive PGP/MIME.
If in the future a new PGP email format becomes popular then it is
possible that new keywords could appear in the value field. It is
recommended that software ignore any keywords which it does not
recognize
and make its format choice based on the keywords that it understands.
I'd like to suggest "inline" as an option (for Outlook users, among
others) as well.
Inline is a subset of partitioned. Partitioned is basically another
word for "use smart ad-hoc encryption of each MIME part into an
encrypted MIME part -- message bodies get inline encrypted, attachments
get file-encrypted." More or less, and generally in no particular
standard ways, this is what most implementations have been doing for 14
years. At some point, it would be worth writing up a definition of how
we're handling all the little cases that come up in the real world for
partitioned encoding, but the one golden rule of partitioned encoding
is full backwards compatibility and thus technically it should not
matter.
