I think we had previously decided to have the model how stats worked here and the actual definition stats in other spec but perhaps we decided something else later.

[vr000m]

What would the model describe? I suppose it should be possible to add some text.

At the TPAC, it was decided to move the entire IDL into the stats-api, so that the definition of RTCStatsType enum and corresponding details would remain in one spec.

I think the discussion at last face to face (which I was not at) contradicts our previous decision on this. I started thread on list. Should resolve there first then decide what to do here.

From the discussion, it seems the consensus is towards making the ref to pc-stats informative. IIUC that be the only change, and the rest of the PR remains the same.

Hey, Voom, just talked to Dan and talk to me about this some time and we can get it sorted out

Closing this one and awaiting a new one according to the discussions we had.
