Yes, but then you shouldn't really be trusting glue records from
the parent (delegating) zone, should you?
I mean, you have to have them in order to break the Catch-22, but
it is my understanding that you should treat them as untrusted and
re-verify them from the authoritative nameservers (if you really care
about that sort of thing).
These are my opinions -- not to be taken as official Skynet policy
