It's always been my position that real compound documents will require
a real compound document format (html is getting there). An MUA can
decide to stick attachments in the body of a message if it wants,
though...that's up to the implementor. 

C-D specifically avoids addressing how to do compound documents
because it's a complex issue, best dealt with in a text or application

Originally the C-D draft had a lot of verbiage about this very
point. That survives today in:

    powerful and flexible approach will be necessary. The
    definition of such approaches is beyond the scope of this
    memo; however, such approaches can benefit from additional
    Content-Disposition values and parameters, to be defined at a
    later date.
