http://www.w3.org/TR/sparql11-query/#matchingRDFLiterals includes the 
following sample data:

    @prefix dt: <http://example.org/datatype#> .
    @prefix ns: <http://example.org/ns#> .
    @prefix : <http://example.org/ns#> .
    @prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

    :x   ns:p     "cat"@en .
    :y   ns:p     "42"^^xsd:integer .
    :z   ns:p     "abc"^^dt:specialDatatype .

Can anyone point me to real-world usage of non-xsd data types like the 
"abc" example here?

thanks,

Bob
