Gavin,

Your latest proposal would fully address my COMMENT.

I agree, and will leave that one untouched.

I will make this change.

To address Éric's point, I propose adding an explanation as follows;

OLD:

   Since the list of record types appearing in "ttl0_data" elements may
   change with time, clients which implement this extension MUST accept
   responses containing values for all valid DNS record types, and
   SHOULD periodically update the list of valid DNS record types to
   align with [IANA-RRTYPES].

NEW:

   Since the list of record types appearing in "ttl0_data" elements may
   change with time, clients which implement this extension MUST accept
   responses containing values for all valid DNS record types, and
   SHOULD periodically update the list of valid DNS record types to
   align with [IANA-RRTYPES], to avoid discarding a recently-added record type.
