1.1. RTCSctpTransport Interface
interface RTCSctpTransport {

4.4.1.1. Constructor
8. Let connection have an [[sctpTransport]] internal slot, initialized to null.
4.3.1.6. 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, set the value of
connection's [[SctpTransport]] internal slot to a newly created
RTCSctpTransport.
