I'd rather not institutionalize advertising in ietf standards.
BUT, if we can get an agreement that all advertisements, of any sort, MUST be labeled with the "advertisement" content-disposition.

Hi, Dean
Sorry for late response. Do you mean "advertisement" content always is needed to 
'render'? So a single content disposition "advertisement" is enough.

In addition, some content body (e.g. Geolocation or advertisement) may be 
inserted or modified by intermediary. Could we specify a common way for 
indicating the source of inserted content body? For example, define a new MIME 
header: Content-Insertedby. A B2BUA may insert a content body including AD like 
this:

Content-Type: text/plain
Content-Disposition: advertisement
Content-Insertedby: AD-Agent <sip: [EMAIL PROTECTED]>

McDonald, i'm lovin' it!

Opinion?

Cheers,
Qian

If we define a new Content Disposition type "advertisement" so that
the operator or service provider may insert advertisement in the all
kinds of message body. And we want the advertisement content 'render'
to the users. Could we use multiple content dispositions
("advertisement" and 'render') for a single content part? Or only
define a new Content Disposition Parameters "advertisement" instead?

So is there a need to ever use "advertisement" in conjunction with something besides "render"?
