Sorry, upon reading this again I do see that Frank is talking about
private-use codes being different from unassigned codes. RFC 3066
allows newly assigned codes but expressly forbids private-use codes. So
the validating processors he is talking about might accept AB
(unassigned but valid) but reject AA (private-use). My mistake.
However, I still contend that existing implementations that validate
their input will need to be updated if they are going to support all the
tags available under RFC 3066bis.
