[CDNi] Secdir last call review of draft-ietf-cdni-delegation-acme-03

[Valery Smyslov via Datatracker <[e-mail]>]

Reviewer: Valery Smyslov
Review result: Ready

I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG.  These comments were written primarily for the benefit of the
security area directors.  Document editors and WG chairs should treat
these comments just like any other last call comments.

This draft defines a CDNI metadata object to enable delegation of X.509
certificates using ACME protocol. The actual operations for certificates
delegation using ACME protocol are defined in RFC9115, which contains a
comprehensive list of security considerations. This document just extends the
CDNI metadata interface to enable leveraging the schemes from RFC9115.

Nits:

1. "CDN" is used in the Abstract without expanding, but it is later expanded in
the Introduction.
   I found this inconsistent: if the abbreviation is well-known, then no
   expanding is needed, otherwise, it should be expanded in the Abstract.

2. "CDNI", "FCI" are used with no expanding before the Terminology section,
which specifies where the terms are defined.
