    Description of Working Group:

    The primary language subtags allowed by the current IANA Language
    Subtag Registry are limited to ISO 639-1 and ISO 639-2 in the same
    way as they were limited by RFC 3066. This covers approximately 500
    possible language subtags. ISO 639-3, scheduled for approval towards
    the end of 2006, will make available around 7000 more code elements
    for identifying languages.

    The working group will prepare an update to the Language Subtag
    Registry procedures to allow the use of 3-letter code elements
    from ISO 639-3 as primary language subtags or extended language
    subtags as appropriate. The working group will also deliver means
    to update the current IANA Language Subtag Registry with the newly
    available subtags.

    The working group will examine, and if necessary clarify or adjust,
    procedures and guidelines with respect to extended language subtags
    and variant subtags. Use cases include the identification of
    signed languages, transliterations, and transcriptions.
    The working group will also consider how the draft work on
    ISO 639-6 may relate to the future development of language tags.

    The working group will clarify text where necessary. It may also
    make adjustments to the registration process and the form of the
    registry if this is deemed appropriate based on ongoing registration
    and operational experience. These adjustments and clarifications
    are not expected to delay the progress of the work.

    Work on the drafts is planned to start before ISO 639-3 is fully
    approved and published. However, the WG will not finalize the
    drafts before ISO 639-3 is fully approved.
