"MIAF AVC1 Baseline profile of HEIF" sounds strange

[wantehchang]

In Section 8.2 we have "MIAF AV1 Baseline profile of [HEIF]".

In Section 8.3 we have "MIAF AV1 Advanced profile of [HEIF]".

These two profile names are complicated and sound strange. I don't know why the profile names are preceded with "MIAF" and follwed by "of [HEIF]", and why they contain "AV1" rather than "AVIF".

Can we change them to "AVIF Baseline profile" and "AVIF Advanced profile" respectively?

From MIAF "A.2 Requirements on the definition of a new MIAF profile"

External organizations may define additional MIAF based profiles to achieve interoperability in their target environments, e.g. by specifying coding formats/profiles/levels conforming to the general MIAF format. However, conformance with the mandatory provisions of this document is required for any format that claims to be a MIAF format.

All of the defined profiles are then named "MIAF XXXX YYYY profile", where XXXX is the codec name and YYYY something like Basic/Advanced/Extended.

So I agree that the text looks slightly weird in AVIF, but I think it makes sense given that we are in fact defining an external MIAF-based profile.

MIAF does not say anything about HEIF, so maybe we can remove the HEIF part.
