Thanks Ned. This approach makes sense, but this is not what I thought you
meant by your first posting.

I think this is the wrong way to go about it. If you want to protect an
entire message including its outermost headers, simply place the entire
message inside your protective envelope using the message/rfc822 construct.
Then strip the outer, unprotected header to its barest essentials.
The process is then reversed by the receiver.
This approach uses nothing but existing media types and can leverage
existing
support for message/partial and message/rfc822. It doesn't require that
you add
additional fields to your structures, with all the attendant deployment
problems that will cause.
The required support for message/rfc822 is attractive, but I am not sure
that is has the correct semantics. Can you explain your idea further?
See above. At most what's needed here is an indicator in the protected
content
that it is to be merged with the outer message header on receipt. That
could
easily be done with either a message-context or a content-disposition field
in
the protected content.
