 | It's lexically legal, of course. There's nothing in the protocol

==> This reminds me of a policy consideration: suppose if the
root-zone allowed a new generation of numeric-only gTLDs and suppose
if those gTLDs accepted on their turn registration of numeric-only
domain names, and so on through the DNS tree... In that case, the
resolution wouldn't fail but we would end up with a real confusion,
wouldn't we?
