Re: draft-ietf-sip-info-events-00: Content-Type vs Info-Package [was RE: draft-ietf-sip-info-events-00: multiple packages per INFO]

Hi,
 
Let's assume I want to send an INFO with package foo.
 
The value of the Info-Package header is "foo", right?
 
Now, what is the value of the Content-Type header?
 
Is it something which is generic for all info packages (e.g. application/info), OR is it something which is specified in the foo package description?
 
Regards,
 
Christer

Christer,

I don't understand where you are heading with this?

If I want to send an INFO with a jpeg, then what is this other mime type
doing other than getting in my way.

OTOH, we haven't discussed Content-Disposition wrt INFO. In the absence
of any mention, I assume that "render" will be used for info packages,
and the detailed processing defined by the Info-Package value.

In some sense, the Info-Package value is serving the same purpose as
Content-Disposition. We could *consider* using the C-D *instead* of the
Info-Package header, so that what we would be negotiating would be the
acceptable C-D values. The downside of that is that we would then need
to open up the registration of new C-D values. I think that might be
opposed by a lot of people.

        Thanks,
        Paul
