  <description
               value="This value set includes codes from [BCP-47](http://tools.ietf.org/html/bcp47). This value set matches the ONC 2015 Edition LanguageCommunication data element value set within C-CDA to use a 2 character language code if one exists,   and a 3 character code if a 2 character code does not exist. It points back to [RFC 5646](https://tools.ietf.org/html/rfc5646), however only the language codes are required, all other elements are optional."/>
