Thanks. I have marked this as "Verified." I changed the type to "Editorial."

Subject: [EXTERNAL] [Technical Errata Reported] RFC7482 (5621)
The following errata report has been submitted for RFC7482,
"Registration Data Access Protocol (RDAP) Query Format".
--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5621
--------------------------------------
Type: Technical
Reported by: John Klensin <john-i...@jck.com>
Section: 2.1
Original Text
-------------
IDN: Internationalized Domain Name
IDNA: Internationalized Domain Names in Applications, a protocol
for the handling of IDNs.
Corrected Text
--------------
IDN: Internationalized Domain Name, a [fully-qualified] domain name
containing one or more labels that are intended to include one or
more Unicode code points outside the ASCII range (cf. "domain name",
"fully- qualified domain name" and "internationalized domain name" in
RFC 8499).
IDNA: Internationalized Domain Names in Applications, a protocol for
the handling of IDNs. In this document, "IDNA" refers specifically
to the version of those specifications known as "IDNA2008" [RFC5980 ff].
Notes
-----
While the proposed new text above borders on the painfully pedantic,
failure to be specific about these things undermines the technical
validity and consistency of the text (making this a technical issue
rather than exclusively an editorial one like a missing reference).
IDNA2008 [RFC5890 Section 2.3.2.3] is very precise about what an
"IDN" is (a definition incorporated by reference in RFC 6365 and
consistent with the definition in RFC 8499) , but there are other
things around that, e.g., assume either that "IDN" refers to a
label, not an FQDN; that an ASCII label, even one in ACE form, does
not make the FQDN in which it is imbedded an IDN; that all of the
label components of an IDN must be U-labels or A-labels, etc. Without
the definition being clear, some of the statements in the document make no
sense.
A reference to 8499 is suggested above because it is the most recent
authoritative definition (and because I didn't write it), but 5980
would be equally legitimate if the authors prefer.
Pinning down the IDNA definition is even more important. While
there are
IDNA2008 references further on in the document, if the question of
what the generic term "IDNA" means is left to the imagination of the
reader, then the specification is missing language about what to do
if, e.g., a query is inconsistent with the U-label form of what is stored in
the registry database
without mapping. The opportunity for that sort of problem is clearly
created
by the "performs any local case mapping deemed necessary" statement
in Section 6.1 of the document, at least unless that case mapping is
constrained to not be applied to domain name labels (which the text
definitely does not say).
Some of the other acronyms in this section of RFC 7482 include references,
so I think it's appropriate for these to be included as well. They do help with
clarity and precision.
