In general, I think the mechanism outlined in
draft-kaplan-sip-info-events-00 is a good starting place for
disambiguating multiple usages of INFO, and I'd like to thank Hadriel
and Christer for putting forth the effort to submit a concrete proposal.
I have a number of specific suggestions for improving the mechanism that
I'd like to offer up at some point in the future.
However, I can't support the document in its current form.
The current document conflates INFO packages with Event packages in a
way that is quite dangerous -- even going so far as to call INFO
packages "Event packages" in a few places (c.f. section 4: "The general
concept is that the UAC generating an INVITE request includes the Event
packages it supports sending and receiving, in two new headers:
Send-Event and Recv-Event."). It confusingly re-uses the "Event" header
field from RFC 3265, and even suggests that common packages can be
defined for RFC 3265 and for INFO.
This harmful conflation between RFC 3265 event packages and INFO
packages pervades the document. Until this issue becomes less confused
in the text, I strongly believe that the document will do far, far more
damage than good.

Howdy,
Just an FYI that Christer and I submitted a draft for SIP INFO events, based on
the email discussion. This is on the agenda for Vancouver.
Cheers,

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : SIP INFO Event Framework
Author(s) : H. Kaplan, et al.
Filename : draft-kaplan-sip-info-events-00.txt
Pages : 12
Date : 2007-11-08
This document defines a proposed solution for defining, negotiating
and exchanging info-event notifications in INFO messages, within SIP
invite-created dialogs, for applications which need to exchange
session-related information inside the invite-created dialog. This
draft addresses issues and open items from RFC 2976, and updates it.
A URL for this Internet-Draft is:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail
readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
