Technical Summary

   The document specifies the 'u-' extension to BCP 47 language tags,
   which provides subtags that specify locale-oriented properties
   (such as calendar, collation, currency, time zone) according to
   work done by the Unicode Consortium in the context of CLDR (Common
   Language Data Repository) and LDML (Locale Data Markup Language).

Working Group Summary

   This document is not the product of any IETF working group.

Document Quality

   The document has been reviewed by various language tagging and
   localization experts. In the context of CLDR (Common Language Data
   Repository) and LDML (Locale Data Markup Language), the proposed
   extension will be used widely. Uses in other localization contexts
   are also possible, because this extension provides a very
   convenient way to extend IETF language tags (BCP47) with the
   usually small missing bits of information to designate a locale.

Personnel

   Martin J. Duerst is the Document Shepherd. Alexey Melnikov is the 
   Responsible Area Director.
