"The NS RR states that the named host should be expected to have a zone starting at owner name of the specified class" (RFC 1034). Also, "delegation point" implies and is used to refer to a "location", i.e., the administrative zone in which the RRsets are governed, rather than the RRsets themselves. Often RFC 4034/4035 use the phrase "at a delegation point". So, while your definitions might be fine, it doesn't seem to me like definitions that refer to a set of records (as opposed to the location of the records) is accurate--at least for the purposes of RFC 4033, which serves as a reference for the RFC 4033/4034/4035 series.
