# GEN AD review of draft-ietf-tls-subcerts-14

CC @larseggert

Thanks to Elwyn Davies for the General Area Review Team (Gen-ART) review
(https://mailarchive.ietf.org/arch/msg/gen-art/QDnSqLec7uKP9GcyuL-8p8nS-2s).

## Comments

### Section 6, paragraph 2
```
     This document also defines an ASN.1 module for the DelegationUsage
     certificate extension in Appendix A.  IANA has registered value 95
     for "id-mod-delegated-credential-extn" in the "SMI Security for PKIX
     Module Identifier" (1.3.5.1.5.5.7.0) registry.  An OID for the
     DelegationUsage certificate extension is not needed as it is already
     assigned to the extension from Cloudflare's IANA Private Enterprise
     Number (PEN) arc.
```
See Martin Duke's comment on using the Cloudflare space; I have the same
question.

### 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 `man`; alternatives might be `individual`, `people`, `person`
 * Term `invalid`; alternatives might be `not valid`, `unenforceable`, `not
   binding`, `inoperative`, `illegitimate`, `incorrect`, `improper`,
   `unacceptable`, `inapplicable`, `revoked`, `rescinded`

### IP addresses

Found IP blocks or addresses not inside RFC5737/RFC3849 example ranges:
`1.3.5.1` and `5.5.7.0`.

## 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

#### Section 4.2, paragraph 1
```

```

### Outdated references

Reference `[RFC5246]` to `RFC5246`, which was obsoleted by `RFC8446` (this may
be on purpose).

### Grammar/style

#### Paragraph 2
```

                                   ^^^^^

Possible typo: you repeated a word.

#### Section 5.1, paragraph 1
```

Use a comma before "and" if it connects two independent clauses (unless they
are closely connected and short).

#### Section 6, paragraph 1
```

This word is normally spelled with a hyphen.

#### Section 7, paragraph 1
```

                             ^^^^^^^^^^^^^^^^^

This word is normally spelled with a hyphen.
