Implement the compare operation on XPath objects: @arg1 <
          @arg2    (1, 1, ... @arg1 <= @arg2   (1, 0, ... @arg1 >
          @arg2    (0, 1, ... @arg1 >= @arg2   (0, 0, ...  When
          neither object to be compared is a node-set and the
          operator is <=, <, >=, >, then the objects are compared by
          converted both objects to numbers and comparing the numbers
          according to IEEE 754. The < comparison will be true if and
          only if the first number is less than the second number.
          The <= comparison will be true if and only if the first
          number is less than or equal to the second number. The >
          comparison will be true if and only if the first number is
          greater than the second number. The >= comparison will be
          true if and only if the first number is greater than or
           equal to the second number.
