Here's my original thinking on the subject.
cdisp was to (and at some point probably will, I envision) feature a
"hidden" disposition type. This is to support compound documents with
links to neighboring bodyparts. What would it mean for a whole message
to be Hidden? Other disposition types might be defined that did not
make sense for whole messages, but only for body parts. Can of
worms. Best to ignore it and declare it illegal at the message level.
If one says a top-level message is an attachment...what's it attached
Your point about the GIF is good, though. Filenames for toplevel
messages, too. maybe we should loosen the spec.
