I think the WG should consider an update to 3261 (likely done through
the process Keith has proposed) that makes this multipart/MIME
mandatory to implement.
I assume that the requirement is that if a message has a
multipart/alternative body, and the UA is capable of understanding one
part of the body, then it must be able to extract that part and use it
to process the message.
While there is a place for multipart/alternative, I think the key
requirement is that if there is a multipart/mixed then the UA should
look within it for one or more parts that it would know how to handle if
they were the only part in the body.
While doing this it also needs to process the handling= parameter on the
Content-Disposition header. It can ignore parts with handling=optional,
but must punt if handling=required on some part and it doesn't know how
to handle it.
Writing down precisely what handling multipart means in sip would make a
nice little draft. I expect there would be at least a bit of controversy
about it.
