Status: Held for Document Update
Type: Technical

Reported by: Kaspar Etter <[e-mail]>
Date Reported: 2020-12-22
Held by: Eric Vyncke (IESG)

Section: 4.1

Original Text
-------------
No "case conversion" or "case folding" is done during such output operations, thus "preserving" case.

Corrected Text
--------------
?

Notes
-----
Whose case is preserved? The case of the label in the DNS query or the case of the label in the DNS database? In other words, if there is a DNS record for ietf.org and I query IETF.org, should the DNS response say ietf.org or IETF.org? I would expect it's the former so that the DNS administrator can inform the DNS requester about the preferred capitalization but I can't figure this out on the basis of the RFC. Does output case preservation refer to something else? All I observe is that tools like dig return the latter when I run 'dig IETF.org'. Maybe an errata is not the right place to ask for clarification but given the name of the RFC, I would expect to find a clear answer to this question in the RFC.

-- verifier note --
After discussion with the RFC author and the errata author, the conclusion is that the RFC isn't wrong but is arguably unclear for some readers.
