Re: MIME's 'Content-Disposition' Header

Main body here refers to the (usually initial) part that contains 
descriptive material. The current dispositions really don't make 
sense in this
context -- such material is inherently inline and not an attachment 
of any

This is sort of contemplating your navel here, but a 
content-disposition of attachment on the main body does make logical 
sense, it's just that most MUA's don't let you compose such a beast.  
If the Content-Type of the message as a whole is Image/gif, then it 
certainly makes sense to indicate that the disposition of that gif 
object might be attachment rather than inline.

So why should this be considered "undefined"?   Granted, MUA's that 
enforce a model of message plus attachments might need to do some 
dancing to represent this to the user, but it's certainly legal MIME.
