| 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. |
