As requested, I have taken a look at treatment of Hold in section 6 of 
draft-ietf-stox-media-02.

The draft says:

    The same semantics are also
    supported by Jingle through the "senders" element and its "initiator"
    and "responder" values.

                  [example to follow]

    In addition to these semantics however Jingle also defines a more
    concise way for achieving the same, which consists in sending a
    "hold" command within a "session-info" action:

Before I can make any useful comments I need to get educated on some 
aspects of xmpp. (I *browsed* XEP 0166, but couldn't quickly figure this 
out.) Hopefully somebody can clue me in on the following:

1) I see that the "senders" element has values that correspond 1:1 with 
SDP sendrecv/sendonly/recvonly/inactive. Are there equivalent 
constraints on O/A behavior? Specifically that:

	Offer    Permissible Answer
	-----    ------------------
	sendrecv sendrecv/sendonly/recvonly/inactive
	sendonly recvonly/inactive
	recvonly sendonly/inactive
	inactive inactive

2) Are the "senders" element values semantically equivalent to the 
corresponding SDP attributes in their implications to how the 
corresponding RTP stream is used?

3)) What are the precise semantics of the "hold" command within a 
"session-info" action? Is it formally equivalent to "initiator" on every 
media session?

	Thanks,
	Paul
