That is what I wrote (with or without drugs. :-))

No it doesn't. ENUM simply records E.164 numbers once assigned. it does not
reflect the process of assignment.

ENUM is not the expression

I am talking very specifically about the authority behind assignment of
E.164 and that is not through the ENUM tree but the E.164 national
delegations.

see above.
