Concise Diagnostic Notation (CDN)
This document formalizes and consolidates the definition of the
Concise Diagnostic Notation (CDN) of the Concise Binary Object
Representation (CBOR), addressing implementer experience.
Replacing CDN's previous informal descriptions, it updates RFC 8949,
obsoleting its Section 8, and RFC 8610, obsoleting its Appendix G.
It also specifies registry-based extension points and uses them to
support text representations such as of epoch-based dates/times and
of IP addresses and prefixes.
// (This cref will be removed by the RFC editor:) The present -25 is
// intended for the May 2026 Working Group Last Call. It corrects a
// clerical error in -24, which completes the work started in PR #102
// and adds a couple of paragraphs on editorial conventions. It also
// makes a leap ahead beyond -24 by adopting and making a detailed
// proposal (PR #105) for a renaming choice that was discussed at the
// 2026-05-13 CBOR interim WG meeting.
