start (RTCDtlsParameters remoteParameters);

dictionary RTCDtlsParameters {
             RTCDtlsRole                  role = "auto";
             sequence<RTCDtlsFingerprint> fingerprints;
};

Which is the purpose of passing multiple remote RTCDtlsFingerprint to the start() method? what should the UA do with them when it comes to verify the remote certificate? Should the UA check all the fingerprints?
