Hello Lars!

We've reviewed the comments you provided. Please see below the proposed 
responses, which will be implemented in the next version of the draft.

> unsigned int(5) vuh_unit_type;

Clarifying language for the pseudocode for the parentheses was added in text. 
In short the integer in the brackets refers to the number of bits allocated for 
the unsigned int.

> This document uses the RFC2119 keywords "SHALL", "SHOULD", "MUST NOT", "SHALL 
> NOT", "MAY", "OPTIONAL", "MUST", and "MUST NOT", but does not contain the

boilerplate.)

Updated boilerplate text was included according to RFC8174.

Wording for "traditional" changed where needed to be more inclusive.

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

## 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.

### Typos

object, usually a pronoun.
