      // types
      typedef DomainT                                  domain_type;
      typedef icl::closed_interval< DomainT, Compare > interval_type;

      // public member functions
      typedef ICL_COMPARE_DOMAIN(Compare, DomainT);

      // public static functions
      static interval_type construct(const domain_type &, const domain_type &);
