Title: Automated Certificate Management Environment (ACME) Device Attestation
Extension Reviewer: Nabeel Cocker Review result: Ready

Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this
Internet-Draft.

The Operational Directorate reviews all operational and management-related
Internet-Drafts to ensure alignment with operational best practices and that
adequate operational considerations are covered.

A complete set of _"Guidelines for Considering Operations and Management in
IETF Specifications"_ can be found at
https://datatracker.ietf.org/doc/draft-ietf-opsawg-rfc5706bis/.

While these comments are primarily for the Operations and Management Area
Directors (Ops ADs), the authors should consider them alongside other feedback
received.

## Summary

Choose one:

- Ready: No issues found. This document is ready for publication.

A couple of minor nits:
- One minor nit in the introduction section: "device /and whether"
- Spelling error in paragraph before section 2: explict > explicit

## General Operational Comments Alignment

The document adds variances to the ACME specification such as a addition of
permanent-identifier, addition of the device-attest-01 challenge type, the
challenge response payload contains a serialized WebAuthn attestation statement
format instead of an empty JSON object ({}) and accounts and external account
binding being used as a mechanism to pre-authenticate requests to an enterprise
CA.

>From an operational consideration perspective it does not define a New
Protocol, a Protocol Extension, or an architecture but provides guidance on
implementing a new type and challenge for certificate issuance using ACME.

The document also cover the IANA considerations indicating updates to the "ACME
Identifier Types" registry and the "ACME Validation Methods" registry.

Thank you to the authors for the effort!

Nabeel
