What a charming document.

I don't see anything in it that indicates a hierarchical name can't
consist of one level, though I see plenty of examples of 2-level names.
If you see text in there that I missed, I'm all ears.

I do see this in RFC 1035, though:

That sounds a lot to me like "hk." is as global as "hk.com."
