Hi benregn,

Yes, an ISO-639-1.

language is one of those params that in hindsight I wish had always been named iso_639_1 but it got pushed out like that two and a half years ago.

Cheers.

As I expected, just wanted to make sure :) The name 'language' is not so much of a problem, it's more that the parameter description field is sometimes empty therefore making one a bit unsure.
