Yes.  SPARQL requires support for the XSD cases of numbers, dateTimes, 
strings and boolean.  XSD F&O provides a large body of work to reuse.

By popular demand, ARQ adds xsd:time, Gregorian dates, and xsd durations 
(much of the real work and details like parsing and range checking is 
actually done by Xerces/J).  And Roman numerals for testing the 
extension mechanisms.
