after kashpureff, circular references are no longer allowed. XYZ.NET
cannot have only nameservers named within within XYZ.ORG, if XYZ.ORG has
only name servers named within XYZ.NET. that's because, due to cache
poisoning risks, out-of-zone glue must be in-bailiwick for the delegator.

i see no reason not to explain it this way in the terminology document,
even though this was an undocumented protocol change. (one of hundreds
of little things that you "just have to know", and this terminology
document would be a fine place to list some of those.)
