@aboba The [[[associated MediaStreams](http://w3c.github.io/webrtc-pc/#dfn-associated-mediastreams)]] is used to create the MSIDs in the SDP.

See the [final steps to create an offer](http://w3c.github.io/webrtc-pc/#dfn-steps-to-create-an-offer):
 * *"3. Given the information that was obtained from previous inspection and the current state of connection and its RTCRtpTransceiver s, generate an SDP offer, sdpString, as described in [JSEP] (section 5.2.)."*

[Section 5.2.1](https://tools.ietf.org/html/draft-ietf-rtcweb-jsep-20#section-5.2.1) says: *"For each MediaStream that was associated with the transceiver when it was created via addTrack or addTransceiver, an "a=msid" line, as specified in [I-D.ietf-mmusic-msid]"*

That seems to refer to the same thing. We should probably make that more explicit if we can.
