Where is XSDDatatypes.XSDIDREFS

Hi,

I've noticed that at the implementation of loadXSDSimpleTypes method in 
XSDDatatype class these lines are commented;

//        tm.registerDatatype(XSDIDREFS);
//        tm.registerDatatype(XSDENTITIES);
//        tm.registerDatatype(XSDNMTOKENS);

Why are these lines commented? I need to use XSDDatatypes.XSDIDREFS, but 
how can I use this datatype?

Thanks.

These datatypes are considered unsuitable for use in RDF:

http://www.w3.org/TR/rdf11-concepts/#xsd-datatypes

[[
xsd:IDREFS, xsd:ENTITIES and xsd:NMTOKENS are sequence-valued datatypes
which do not fit the RDF datatype model.
]]
