Hi,

The "WHIP session" terminology is confusing.

Q1:

The definition of WHIP session is:

   *  WHIP session: Indicates the allocated WHIP session by the WHIP
      endpoint for an ongoing ingest session.

This does not define what a WHIP session is, as the definition text contains the terminology it is supposed to define :)

---

Q2:

"WHIP session" seems to refer to a session created for WHIP, e.g. based on the following definition:

  *  WHIP endpoint URL: Refers to the URL of the WHIP endpoint
      responsible for creating the WHIP session.

So far so good, but in addition "WHIP session" also seems to refer to some functional entity within the session, which is confusing. The text talks e.g., talks about "sending requests to the WHIP session" and "the WHIP session MUST do X", and the call flow shows "WHIP session" as a functional entity.

I do understand that "WHIP session" is not a "physical box", but a function/resource that is dynamically created for each WHIP session by the WHIP endpoint, but I think using the same terminology for referring to a session and a function is confusing. 

Perhaps using "WHIP session resource" or something, and define it as a dynamically created function that will do X and Y?

Regards,

Christer
