So if you are going to prefix RTCPeerConnection, these seem like they should be prefixed as well. I appreciate that there are disagreements about whether we should prefix anything, but once you are going to, you should be consistent. * In the process of building an interoperable WebRTC application > between Chrome and Firefox, when I did not provide > DtlsStrpKeyAgreement to true as an optional constraint to Chrome, > Firefox would fail to establish the handshake by reporting an error > of "DCB has not been created" during the addIceCandidate function. > Why is this the case? > There seem to be several questions. - Why doesn't it work? Because the offer without DTLS is incompatible with Firefox, which requires DTLS. - Why is there a lame error message?

We think the spec is wrong and is likely to change.
