Artart last call review of draft-ietf-mmusic-rfc8843bis-04

Reviewer: Claudio Allocchio
Review result: Ready

The document is consistent and ready for publication.
Just as a style comment: section 1.4 is a bit unusual in an RFC, specifically
by mentioning what happened during one IETF meeting, etc. Nothing wrong with it
but it mixes a specification (the RFC resulting for publication) with historic
actions. Maybe there is a way to avoid this by changing a bit the text of the
1.4 section.

Another comment: again all fine! but when a document like this updates/fixes
other documents, including errata, new text replacing sections in other
documents, etc, the implementer has a challenging task in putting the pieces
together. I'd for the future suggest not to use this "amendment" technique, but
to publish complete updated RFCs versions instead.
