Title: Session Timer: Support header in 200 OK response

Hello everybody,
suppose I have a device supporting and requaring the Session-Timer feature.
It sends an INVITE message including the following headers.

        INVITE .....
        .......
        Require: timer
        Supported: timer
        Session-Expire: 3000, refresher=uac

Is a 200 OK response requiring the Session-Timer without the Supported header correct?

        .... 200 OK
        .....
        Require: timer
        Session-Expire: 3000, refresher=uac

I think the UAC should perform the refresh because the Require header is present even if the Supported is not present.
I think in "draft-ietf-sip-session-timer-11.txt" is not clear if the Support header must be present into the response.

Let me know your opinion
Regards
Lorenzo
