True. The code will probably accept the pattern then fail trying to use the
string.
If the client sends the form with a zone.

For some reason, the smarter the person, the less likely they are to
read any of the documentation before using some software.
I call it the "it should work the way I would design it" phenomenon :-)

You have to admit that Acee's suggestion is more intuitive than the current
definitions.

Clearly an NBC change.
IMO it is more useful to put some YANG extension magic in these specific
typedefs
than just bumping a major revision number. This is a great use-case for the
version DT.

There probably is no solution path where nobody has to change any YANG or
any code
and everything still works.
