Property language : WideString; (Read/Write)
The human language of the content. Valid codes are taken from the IETF RFC 3066. If this attribute is null, the language may be inferred from elsewhere, either from the context or from unicode language tags, for example.
Conformance profiles SHOULD define defaulting rules for language for a given usage environment of this specification.
Note: While language attribute usually alters the interpretation of the text, the language attribute does not alter the meaning of the characters in the text.
