The consistent word for this in 1035 is simply "message". "DNS Message" is in more common use today, I would say. The text you quoted from 1035 is most usefully interpreted as a contraction of "messages sent over UDP"; "UDP message" really doesn't have a well-understood meaning, and is easily conflated with "UDP datagram" which does not have a size limitation of 512 bytes.
