URI.datatype 

The xsd:anyURI type and thus URI references in SCXML
documents may contain a wide array of international
characters. Implementers should reference RFC 3987 and
the "Character Model for the World Wide Web 1.0:
Resource Identifiers" in order to provide appropriate
support for these characters in VoiceXML documents and
when processing values of this type or mapping them to
URIs.
