Simple chat. Gen-ART comments

When Suresh did the Gen-ART review of the SIMPLE chat draft, he had two 
comments. Here is a proposal for his resolution. Please comment, 
especially if you disagree or can improve the text:

1) REQ-3: It is unclear why this is separate from REQ-2. In my reading,
REQ-2 already covers REQ-3.

I propose to make REQ-2 a requirement to identify the sender and REQ-3 a 
requirement to identify the recipient. My proposal:

    REQ-2:  A conference participant must be able to determine the
            identifier of the sender of received instant messages.  Note
            that the actual identifier depends on the one which was used
            by the sender when he or she joined the conference.

    REQ-3:  A conference participant must be able to determine the
            identifier of the recipient of received messages.  For
            instance, the recipient of the message might be the entire
            conference or a single participant of the conference (i.e., a
            private message).  Note that the actual identifier may depend
            on the one which was used by the recipient when he or she
            joined the conference.

2) Section 6.1

This sentence is not clear. Can you clarify/reword.

"Having the header of the Message/CPIM wrapper only in the first chunk,
the MSRP switch MUST track the Message-Id until the last chunk of the
message has been distributed."

I'm fine with REQ-2. For REQ-3, who is the participant? Are we talking about the sender, the recipient, or
someone else? In the case of a sender, the operative word is probably "select" rather than "determine".
