};

  6.1.1.

    interface RTCSctpTransport {

        readonly attribute RTCDtlsTransport      transport;

        readonly attribute RTCSctpTransportState state;

        readonly attribute unrestricted double   maxMessageSize;

                 attribute EventHandler          onstatechange;

};

  4.4.1.1.  Constructor

    9.      Let connection have an [[SctpTransport]] internal slot, initialized to null.

  4.4.1.6.  Set the RTCSessionSessionDescription

    2.2.6.  If description is of type "answer" or "pranswer", then run the

            following steps:

      1.    If description initiates the establishment of a new SCTP association, as defined in

            [SCTP-SDP], Sections 10.3 and 10.4, create an RTCSctpTransport with an initial state

            of "connecting" and assign the result to the [[SctpTransport]] slot.
