I know of at least 2 commerically-available DNS maintenance systems
that, by default, do not allow what they call "dotted hostnames", by
which they mean a name which is at least 2 labels below a zone cut, e.g.
"foo.bar" in the "example.com" zone. Their underlying assumption seems
to be that *every* level of the hierarchy will, in the
usual/typical/default case, be delegated.
I don't agree with this assumption in the slightest, but some people are
afraid of changing default behaviors...
