Permissible values

The syntax for preferredLanguage is derived from BCP47:

langtag = language ["-" region]
language = 2*3ALPHA ; shortest ISO 639 code
region = 2ALPHA ; ISO 3166 code

The language tag is composed of a primary language (two-letter ISO639 language code) and an optional region (two-letter ISO3166-1 country code).
