The following errata report has been held for document update for RFC8610, "Concise Data Definition Language (CDDL): A Notational Convention to Express Concise Binary Object Representation (CBOR) and JSON Data Structures". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid6278 -------------------------------------- Status: Held for Document Update Type: Technical Reported by: Eric Seppanen <eds@reric.net> Date Reported: 2020-09-04 Held by: Barry Leiba (IESG) Section: Appendix B Original Text ------------- BCHAR = %x20-26 / %x28-5B / %x5D-10FFFD / SESC / CRLF Corrected Text -------------- BCHAR = %x20-26 / %x28-5B / %x5D-7E / %x80-10FFFD / SESC / CRLF Notes ----- Between draft 6 and 7 of the RFC, the ASCII DELETE character 0x7F was excluded from the character set allowed in text literals. I believe it should also be excluded from the character set of bytestring literals. A 0x7F byte could not be decoded if included in a hex or base64 bytestring, leaving only UTF-8 bytestrings. Since there is no discussion in the text of any reason to allow this character in a UTF-8 bytestring when it was not allowed in a UTF-8 text string, I suspect this was an oversight. ===== Verifier notes ===== It was, indeed, an oversight, but discussion on the CBOR working group list shows that the proper fix is not straightforward, and that it should be handled in the next version of the spec. -------------------------------------- RFC8610 (draft-ietf-cbor-cddl-08) -------------------------------------- Title : Concise Data Definition Language (CDDL): A Notational Convention to Express Concise Binary Object Representation (CBOR) and JSON Data Structures Publication Date : June 2019 Author(s) : H.
