For example, we don’t have this one: http://xml2rfc.tools.ietf.org/public/rfc/bibxml3/reference.I-D.draft-abarth-cookie-02.xml (There’s nothing here: https://github.com/ietf-ribose/relaton-data-ids/blob/main/data/draft-abarth-cookie-02.yaml) It exists on xml2rfc server, but we don’t import it into our sources? If that’s intentional, feel free to close.
