The RTCPeerConnection decodes the contents and validates that it contains a + fingerprint value for every a=fingerprint attribute in the session description. + This ensures that the certificate used by the remote peer for communications + is covered by the identity assertion. + + [RTCPeerConnection-peerIdentity] + 9. The RTCPeerConnection validates that the domain portion of the identity matches + the domain of the IdP as described in [RTCWEB-SECURITY-ARCH].
