I've just found that there's actually a LocaleIdentifierValidator, so 
that's all I need :-)

BTW any idea how long a fully qualified locale identifier can be? I had 
start with a naive 5-character length (assuming the form was xx_YY), but 
I see that it can be much longer. I've settled on 50 for now, is that 
safe enough?

Cheers
