Hi Henrik,
  Thank you for your reply. I commented it in the GitHub https://github.com/w3c/webrtc-stats/issues/388. I will continue following this thread in the GitHub. My comments in the GitHub,

I think the Conformance<https://w3c.github.io/webrtc-stats/#conformance> should be updated if it is really out of date.
I do see Google and Apple implemented the fractionLost in the inbound-rtp, which is useful to me. If the industry has implemented it in the real web browsers, I think it is good to make it official to all browsers.

Hello! fractionLost is part of RTCRemoteInboundRtpStreamStats (remote-inbound-rtp), not RTCInboundRtpStreamStats (inbound-rtp). The mandatory list<https://urldefense.proofpoint.com/v2/url?u=https-3A__w3c.github.io_webrtc-2Dpc_-23mandatory-2Dto-2Dimplement-2Dstats&d=DwMFaQ&c=fxtm8VyUXgCVDKhi9yIVsVsjq1ocZ-LZVehzdzjopw0&r=rU6fySv86v_DBRoPOwMfYacJob2HbOj1vEX6AKZaU10&m=Yb9KW1MMqtWXG0JKY2QkntgdLtcN1KEXdzIykyMeC7Q&s=FrbIyO6ZFTG6K3QNOlDnrMVKcf-1LQW6gtanKcfRuuQ&e=> (defined in webrtc-pc, not webrtc-stats) of this dictionary includes "all required attributes from its inherited dictionaries, and also attributes localId, roundTripTime". So currently it does not mandate fractionLost, and it sounds like the conformance<https://urldefense.proofpoint.com/v2/url?u=https-3A__w3c.github.io_webrtc-2Dstats_-23conformance&d=DwMFaQ&c=fxtm8VyUXgCVDKhi9yIVsVsjq1ocZ-LZVehzdzjopw0&r=rU6fySv86v_DBRoPOwMfYacJob2HbOj1vEX6AKZaU10&m=Yb9KW1MMqtWXG0JKY2QkntgdLtcN1KEXdzIykyMeC7Q&s=u3CjX-qJZc5AdUeTPqeZ2pImSP4yimwvhJNJCCDdXvM&e=> section (of webrtc-stats) which recommends what other documents might mandate (without being authoratative?) is out-of-date.

However, the top of this web page has the statement as below,

An implementation MUST support generating statistics for the type RTCInboundRtpStreamStats, with attributes packetsReceived, bytesReceived, packetsLost, jitter, and fractionLost.

The fractionLost is in the “MUST” support. But it is missed in the dictionary below
