Technical Summary

   The Concise Data Definition Language (CDDL), as defined in RFC 8610
   and RFC 9165, provides an easy and unambiguous way to express
   structures for protocol messages and data formats that are
   represented in CBOR or JSON.

   The present document updates RFC 8610 by addressing errata and making
   other small fixes for the ABNF grammar defined for CDDL there.

Working Group Summary

   The consensus backing the document was widespread at adoption time (adopting
   a bundle of documents), and became more quiet up to the WGLC. That fits the
   nature of the document: it is "boring" in the sense that it packs up errata
   items and small fixes.   No controversial points. No extreme discontent.

Document Quality

   The implementation at https://github.com/cabo/cddlc/ supports both the new
   mechanisms and follows the errata resolution. Other implementations have not
   taken up the changes, but are often not even in a position to need them.
   (For example, the cddl Rust crate and the cddl Node.js implementation use
   more lax rules for escaped strings anyway; the Node.js implementation does
   not support generics in the first place).

   The Document Shepherd for this document is Christian Amsüss. The
