When adding information such as PersonName to an RM object, the serialization to XML is incorrect. The spec says (and shows on page 126 of the 1 Nov 2008 version), that this element should be of type xpil:PartyType.
This does not validate against the normative reference schema's. the PersonName structure should be wrapped in a PartyName element.
