This is extremely interesting and helpful; thanks.  I wonder about
something, though.  What should we call the state you get when you
have a validating resolver that can only speak to upstream resolvers
that all respond NOTIMP (or similar) to the DO bit?  That case appears
to be covered by the 4035 definition and not the 4033 one.  Is this
"unvalidatable" rather than "indeterminate"?

Best regards,
