The following errata report has been submitted for RFC6844,
"DNS Certification Authority Authorization (CAA) Resource Record".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=6844&eid=4515

--------------------------------------
Type: Technical
Reported by: Tom Clegg <tom@tomclegg.ca>

Section: 4

Original Text
-------------
   o  If A(X) is not null, and R(A(X)) is not empty, then R(X) =
      R(A(X)), otherwise


Corrected Text
--------------
   o  If A(X) is not null, and CAA(A(X)) is not empty, then R(X) =
      CAA(A(X)), otherwise


Notes
-----
R is the algorithm being described here, so R(A(X)) means a recursive search on the CNAME target, including its parents. However, the example that follows, Parent(Alias(x.y.z)) is not part of the search. Either the algorithm is incorrectly specified, or the example is incomplete.

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party (IESG)
