I think it important to distinguish between content-type and
disposition. Content-Type should indicate the kind of data in a
bodypart, not it's placement in the body of the message. If you make
attachment an application subclass, where do you specify the
application that created the attachment? In a parameter?? Ugly.
A Content-Disposition header separates these two attributes neatly.
This is not to say that a compund document type should not be an
application subclass: the point is that in the absence of a viewer for
the compound document, your MUA can still get a hint as to display
semantics from the Content-Disposition header, without loss of
Content-Type information about the body part. For Sun's mailtool, I
would expect something like:
Content-Type: application/X-Framemaker; version = 3.1;
Content-Transfer-Encoding: Base64
Content-Disposition: attachment
Content-Id: 12345(_dot_)12367(_dot_)FOO(_at_)bar(_dot_)frobbed(_dot_)edu
(etc)
