2. RFC 7344 および RFC 7477 の更新

Section 4.1 of [RFC7344] lists acceptance rules for CDS/CDNSKEY records. This document extends that list with the consistency requirements defined here and does not modify any other part of [RFC7344].

Sections 3.1 and 4.2 of [RFC7477] decide from which nameserver to query CSYNC information. This document replaces that logic with the CSYNC consistency requirements defined here.
