Hi,

A couple of comments:

First, in general, if we are going to update the reference version, we need to verify that we don't break anything.

Second, most of the RTCWEB RFCs referencing the WebRTC spec seem to reference *without* a version (i.e., https://www.w3.org/TR/webrtc/). Many RFCs also reference to RFC 8825 for WebRTC, and RFC 8825 also reference WebRTC without a version.

So, is there a reason why we would use a version in JSEP, while not in other RFCs? Note that often the WebRTC reference is Normative.

I do understand that JSEP is very closely linked to WebRTC, why there might be a need to reference a given version. But, then again, we need to make sure that updating the version does not break anything.

Regards,

Christer

Thanks Sean.  I finally concluded that was the intent.  And I think
technically it says so.
If you could look at making that more clear early, it would probably
help those readers who are not as familiar with the cited W3C API.

Yours,
Joel
