Apologies. I was wrong. Andy is correct. "base sn:configurable-encoding;" should be added to the transport protocol identities and an errata to https://datatracker.ietf.org/doc/html/rfc8639#appendix-A should be filed. Errata 8073 should be rejected.
See: https://mailarchive.ietf.org/arch/msg/netconf/BRzA6DoJKgQd1twikAalC8TNqzE/

It appears that draft-ietf-netconf-https-notif is missing the update.
