https://www.rfc-editor.org/errata/eid8523

--------------------------------------
Status: Verified
Type: Technical

Reported by: David von Oheimb <David.von.Oheimb@siemens.com>
Date Reported: 2025-08-01
Verified by: Paul Wouters (IESG)

Section: 2

Original Text
-------------
PKIMessages

Corrected Text
--------------
PKIMessage structures

Notes
-----
This pertains to all three occurrences of the word "PKIMessages" in sections 2, 2.3, and 2.5.

"PKIMessages" can be misinterpreted as the ASN.1 type "PKIMessages", defined as:

    PKIMessages ::= SEQUENCE SIZE (1..MAX) OF PKIMessage

Yet what is meant in all three occurrences in this RFC is simply: PKIMessage structures 
(i.e., one ore more structures of type PKIMessage), not a list/sequence of PKIMessage.

Note: The same disambiguation has already been done in RFC 9811 
(as mentioned in https://datatracker.ietf.org/doc/draft-ietf-lamps-rfc6712bis/10/)
