Hi,
I suggest Content Indirection Mechanism defined in rfc4483 should also be
considered in this draft.
It is a little special, an example from rfc4483:
6.1. Single Content Indirection
INVITE sip:[EMAIL PROTECTED] SIP/2.0
Accept: message/external-body application/sdp
Content-Type: message/external-body;
ACCESS-TYPE=URL;
URL="http://www.example.net/party/06/2002/announcement";;
EXPIRATION="Sat, 20 Jun 2002 12:00:00 GMT";
size=231
Content-Length: 105
Content-Type: application/sdp
Content-Disposition: session
Content-ID: <[EMAIL PROTECTED]>
In addition, what happens to the INVITE request if the recipient can not get
the indirect content?
Nits: a letter "l" is missing in the title.

Cheers,
Qian

The other classic example, because it is just like email, is MESSAGE
with a multipart/alternative containing plain text and html.
