        // example, it is possible to restrict a datatype using facets from XML
        // Schema Datatypes. For example, lets create a data range that
        // describes integers that are greater or equal to 18 To do this, we
        // restrict the xsd:integer datatype using the xsd:minInclusive facet
        // with a value of 18. Get hold of a literal that is an integer value 18
        OWLLiteral eighteen = factory.getOWLLiteral(18);
        // Now create the restriction. The OWLFacet enum provides an enumeration
        // of the various facets that can be used
        OWLDatatypeRestriction integerGE18 = factory.getOWLDatatypeRestriction(
                integer, MIN_INCLUSIVE, eighteen);
        // We could use this datatype in restriction, as the range of data
