One might renegotiate on a re-INVITE, or on any transaction. I believe
Christer was proposing the latter. I think restricting INFO package
negotiation to dialog-forming and dialog-reforming transactions is
reasonable.

Dean,
I'm now confused on what you are advocating.
As its currently written, you can negotiate which packages you want
to use. The later in the call you can renegotiate to use different
ones. That seems consistent with what you are saying. So what is the
issue?
Thanks,
Paul

Hi,
Not only 3pcc, I think it could be useful to re-negotiate the
packages during the session. For example, I may want DTMFs only
during a certain period of the call, so for the rest of the call
you would not be able to generate INFOs by pressing digit buttons.
Also, we may enable some application during the call, so the UAs
need to re-negotiate the packages. For example, I may tell you
that I have a vcard which I want to send you, but we may not have
negotiated that "by defualt" when the call was established.
then re-INVITE.
