What I was trying to say it, that both registrat and root (if possible)
should check if the glue belongs under registered domain. If not, the glue
should not be accepted.

If I register example.com, it's OK to register _anything_.example.com as
glue. However, registering _anything_.example.net should not be accepted.

I wonder how is it possible that anyone accepts that.
