After the confusion around RTCIceCredential OAuth parameters in
WebRTC-PC, I just want to close the gap between W3C WebRTC-PC and IETF
RFC7635 is complex and confusing without a guide.
My intention was to remove confusion and define an example guideline
howto use RFC7635 in WebRTC context, and put all this info into the
WebRTC-PC spec.

Now I see I went too far, and PC spec should step back and mention OAuth
PoP only as a possible way of the key distribution, but in other hand
the information in webrtc PC is inline with the RFC7635 example Appendix B.

Is it better to leave totally undefined howto use RFC7635 in WebRTC
context as Harald proposed?
I am not sure.
