# genart review of draft-ietf-avtcore-rtp-v3c-12

CC @larseggert

## Comments

This is in good shape, No specific concerns.

### Section 4.3.1, paragraph 3
```
      unsigned int(5) vuh_unit_type;
```
What does the parenthesized integer indicate? Am not familiar with this style of pseudocode.

### Boilerplate

This document uses the RFC2119 keywords "SHALL", "SHOULD", "MUST NOT", "SHALL
NOT", "MAY", "OPTIONAL", "MUST", and "MUST NOT", but does not contain the
recommended RFC8174 boilerplate. (It contains a variant of the RFC2119
boilerplate.)

### Inclusive language

Found terminology that should be reviewed for inclusivity; see
https://www.rfc-editor.org/part2/#inclusive_language for background and more
guidance:

 * Term `traditional`; alternatives might be `classic`, `classical`, `common`,
   `conventional`, `customary`, `fixed`, `habitual`, `historic`,
   `long-established`, `popular`, `prescribed`, `regular`, `rooted`,
   `time-honored`, `universal`, `widely used`, `widespread`

## Nits

All comments below are about very minor potential issues that you may choose to
address in some way - or ignore - as you see fit. Some were flagged by
automated tools (via https://github.com/larseggert/ietf-reviewtool), so there
will likely be some false positives. There is no need to let me know what you
did with these suggestions.

Did you mean "associating"? Or maybe you should add a pronoun? In active voice,
"allow" + "to" takes an object, usually a pronoun.
