Identifies the starting ordinal, numbered from 1,
              for an array element of index _array_structure_list_section.index
              in the section.
              The value defaults to 1.   For the given index, the elements in
              the section are of indices:
              _array_structure_list_section.start,
              _array_structure_list_section.start
                 + _array_structure_list_section.stride,
              _array_structure_list_section.start
                 + 2*_array_structure_list_section.stride,
                  ...
              stopping either when the indices leave the limits of the indices
              of that dimension or
              [min(_array_structure_list_section.start,
                  _array_structure_list_section.end ),
               max(_array_structure_list_section.start,
                  _array_structure_list_section.end )].
              The ordering of these elements is determined by the overall
              ordering of _array_structure_list_section.array_id  and not by
              the ordering implied by the stride.
