If there is a well-accepted name for "address records that come with glue records but are not actually glue records", we can add it, but I am hesitant for this document becoming a list of things observed in the wild that don't already have names. FWIW, what we tentatively have for the next draft is: Glue records -- Resource records which are not part of the authoritative data [for a zone], and are address resource records for the servers [in a subzone]. These RRs are only necessary if the name server's name is "below" the cut, and are only used as part of a referral response.
