The RFC 3066(bis) standard that is maintained by the Internet Engineering Task Force (IETF) defines an IETF language tag, which provides a uniform means of identifying a language. The format of an IETF language tag is similar to the culture name returned by the Name property, but does not identify a culture uniquely. That is, different cultures can share the same IETF language tag if those cultures have identical linguistic characteristics. The linguistic characteristics of a culture are contained in the TextInfo object associated with a CultureInfo object.
An IETF language tag consists of a mandatory language identifier, an optional script identifier, and an optional region identifier. For example, a valid IETF language tag for the Serbian language, the Cyrillic script, and the region of Serbia is "sr-Cyrl-SR".
