Dear all, Today, I released a new version of the draft: https://datatracker.ietf.org/doc/html/draft-yocto-dns-relative-label-02. I replaced the term "record" with "resource record", updated the reference to the EDNS RFC, and added an Acknowledgements section. @Peter Thomassen: Is it possible

Scott, Yes, new qualified names (identifiers) for new things will disambiguate from existing names. The important thing is to avoid a truly "split horizon" DNS situation where the same qualified name means different things in different contexts (the lack of specific records visible from a contex

This is not needed. Additionally when answers are returned the zone is not known. This is true of both stub resolvers and non validating recursive resolvers. As for your MX example one could use existing DNS compression mechanisms on the wire and when storing the record if desired by using an of

This expectation setting. Adjusting key generation won’t happen unless there is a written requirement for it to happen. If we where to say duplicate keys tags are no longer supported as of date X there is no way the operators of all the existing signed zones with duplicate tags would know to perfo

Even if we where to go with one failure is allowed we still need to write down the new rules and there will be complaints that we are retrospectively changing the rules. This is grand fathering in the old rules for the old algorithms. Write a BCP, not a standard disallowing key id clashes. Ri
