Jim:
So, how about the following first
paragraph instead:
The principal objective of this content type is to convey
cryptographic keying material from a source to a destination.
This might be in response to the receipt of an
application/mosskey-request content type or it might be in
anticipation of receiving an application/mosskey-request if it
is not sent, e.g., it may be combined with a multipart/signed
object by an originator to ensure that a recipient has the
cryptographic keying material necessary to verify the signature.
When combined with other content types, the processing by a
recipient is enhanced if the application/mosskey-data content
type is positioned in its enclosing content type prior to the
content types that will make use of its cryptographic keying
material.
Thanks, Jim. This satisfies my concern.
