An IETF language tag is a standard identifier for a human language or dialect. It is a short string of text; an example is "en-US".
A language tag consists of a sequence of hyphen-separated subtags, which define and refine the language.
Registration of subtags is handled by IANA. Language tags are no longer registered directly.
