- Quoting from RFC 1341:
-
- However, unlike Content-Types and subtypes, the creation of
- new Content-Transfer-Encoding values is explicitly and
- strongly discouraged, as it seems likely to hinder
- interoperability with little potential benefit. Their use
- is allowed only as the result of an agreement between
- cooperating user agents.
-
- What's wrong with merely using a new Content-Type, something like
- application/x-pgp or message/x-pgp, and having an encapsulated
- Content-Type: contain the actual variety of data?
-
- Or, you could model it after the MIME-PEM standard, and make a
- multipart/x-pgp type. That would be the ideal solution, but it's only
- worth doing if you thing PGP's current mechanism for message
- formatting will really become the (or at least a) long-term standard.
-
- Including version is a good idea, but it doesn't need to be part of
- the subtype, you can just throw in version=2.1.
-
- Creating a new Content-Transfer-Encoding is a very bad idea.
