1. Section 6.1 includes a question whether it is OK to prohibit
Send-Info/Recv-Info in re-INVITE or UPDATE, and mentions that Adam
points out 3PCC needs it. I agree with Adam.

2. There is no provision for Send-Info/Recv-Info in 200/ACK (i.e.
omitting from an INVITE request, in the same way that SDP offer can be
omitted). It seems to me that some of the use cases that motivate INVITE
without SDP offer could also motivate INVITE without
Send-Info/Recv-Info. For example, a 3PCC make-call might need to do
this.
Yep. It is usually my role to remind people that it isn't done until it works with 3PCC. But thats true regardless of who does the reminding.
