IETF Publishes New Language Tag Specifications

The Internet Engineering Task Force (IETF) has published two new specifications for language tags. RFC 4646: Tags for the Identification of Languages replaces RFC 3066 and, with the new IANA Language Subtag Registry, extends language tag syntax to address a number of long-standing issues. The separate RFC 4647: Matching of Language Tags addresses how to match the new tags. The W3C I18n GEO Working Group provides a gentle introduction to the new syntax.
