** xs:string to xs:token **
** **
** 08/24/2004: 1) To correct a XML Binding to Marshalling issue, a change **
** is needed to resolve a naming convention for two complex **
** types: **
** 1.1) Changed the name of the LangString complexType **
** to LanguageString **
** 1.2) Change the name of the langString completType to **
** LangString **
** 2)Updated the Creative Commons Licensing agreement to **

** extensions. The LanguageId will now vaidate any **
** language defined by 1484.12.3 and the token "none". **
** 3)Updated VCard to support attribute extensions. **
** 4)Updated LanguageString to reference the xs:language **
** data type. **
** 5)Updated DateTimeValue to support attribute extensions. **
** 6)Updated DurationValue to support attribute extensions. **
