| 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. |
