draft-ietf-dnsop-dns-error-reporting

Hi!

I was assigned a review of draft-ietf-dnsop-caching-resolution-failures, for an INTDIR Telechat Review.

Review of	draft-ietf-dnsop-dns-error-reporting
Type	Telechat Review
Team	Internet Area Directorate (intdir)
Deadline	2023-12-09
Reviewer	Carlos Pignataro 


In general, I found the document to be useful and clear, effectively organzied, and easy to follow for an implementor. 

Please find below only some minor nits for consideration:

1. Append a comma after "i.e.".

2. Change "Well known" to "Well-known".

3. Capitalization of "RRset" vs. "RRSet", although RFC 8499 mentions both.

4. Should RFC 2199 be a Normative reference instead of Informative?

Thanks!

Carlos.
