pretty much. And to distinguish those, you need more than C-T.
But I think as we have been discussing, if we only allow one info 
package per INFO, then the Info-Package header belongs in the message, 
not in the body part.

I'll revise your example a bit:


INFO sip:[email protected]
To:...
From:...
Some-Header: CID:abcdefg
Info-Package: foo
Content-Type:multipart/mixed
Content-Length:...

--boundary
Content-Type: application/foo-data
Content-Disposition: package;handling=required

foo data
--boundary
Content-ID: abcdefg
Content-Type: application/some-header-data
Content-Disposition: by-reference;handling=optional

some other (non-info package) data
--boundary--


In the above I have used C-D of "package" to identify the part that 
contains the info package. That is yet to be determined, but I think it 
needs to be well defined, even if it is "render".

A more straightforward case would be:

INFO sip:[email protected]
To:...
From:...
Info-Package: foo
Content-Type: application/foo-data
Content-Disposition: package;handling=required
Content-Length:10

foo data
