    It's pretty simple, actually. ISO 639-3 and ISO 639-2 share a codespace.
    That is, if you see a code 'xyz' in ISO 639-2, it will have exactly the
    same meaning in ISO 639-3. If you see a code 'xyz' in ISO 639-3, if it
    is assigned (or becomes assigned) in ISO 639-2 it will have exactly the
    same meaning.

    No language will have two codes assigned in the registry. Users will,
    presumably, choose the code that best meets their needs.
