it does not assume that all countries (or parts of countries, by the way)
have only one official language, it assumes that if no additional language
is given the value is in the official language of the country or area that
is tagged. If there are more than one official language it is clear that
the language component cannot be omitted.

On the other hand, for languages that are different from the official
language (b), it will be hard to determine which term is the officially
allowed or prescripted version in the country, at least as long as it has
not been judged in court or otherwise officially determined. How would it
be verifiable?

I believe "official name" is a very good tag when there is an official
naming convention, other cases should get different tagging.
