Internationalization Tag Set (ITS)

This document defines data categories and their implementation as a set of elements and attributes called the Internationalization Tag Set (ITS). ITS is used with new and existing schemas to support the internationalization and localization of schemas and documents. Implementations of ITS are provided for three schema languages: XML DTDs, XML Schema and RELAX NG. In addition, implementations are provided as fixed modularizations of various existing vocabularies (e.g. XHTML, DocBook, Open Document). The definition of the data categories is still in an early draft stage.
