The only reason why those templates are static is so users can overwrite
the exception messages. That was useful when we didn't have a handy
translator, but now that we can define a translator through the Factory,
this is not needed anymore.
Besides, having those properties public adds complexity to the code.

According to the official documentation [1] the correct way of writing
the "inheritDoc" tag is with the uppercase "D".

The "AbstractSearcher" already does most of the job that "CountryCode"
was doing, so using it as parent class made more sense. That also makes
the validation case-sensitive which is not a problem since the standard
ISO 3166-1 in fact enforces an specific case for the country codes.
The documentation about the rule is also updated.
