Thanks for the pointer. https://www.ietf.org/archive/id/draft-ietf-i2nsf-nsf-facing-interface-dm-29.html Search for “leaf language {” or use a Chrome-specific URL: https://www.ietf.org/archive/id/draft-ietf-i2nsf-nsf-facing-interface-dm-29.html#:~:text=leaf%20language%20%7B So they did copy the ABNF from RFC 5646, turned it into a regex, and copied it in… Maybe the regex we have in https://github.com/core-wg/core-problem-details/pull/40 would have been a bit more easy to handle.
