Stability of valid IDN labels

I don't think I confuse the application of ISO 3166-1-alpha-2 code 
values to the DNS with anything else. In this discussion, it defines the 
(impermanent) validity of two octet sequences in the root zone, which is 
a syntax, however cumbersome.

However, my point was to the temporal properties of some requirement, in 
the first instance, the "syntactic (in)valid forever" statement in 
Mark's note of the18th, or Vint's "on the other hand" response to you of 
today, mentioning "... previous registrations would then not work ...".

Both assume a temporal property ("permanence") requirement I'm 
unfamiliar with. It appears my example didn't illuminate the problem of 
identifying the origin and purpose of the "forever requirement", and is 
functioning as a distraction.

That wasn't my intent. Identification of a requirement for a temporal 
property is my intent.
