163 * element indexes that, instead of memoizing in the softc, we calculate
164 * on the fly during the traversal of the element objects. The various

168 * individual elements (no overal status elements) of particular types.
170 * To use an iterator, initialize it with ses_iter_init(), and then
171 * use ses_iter_next() to traverse the elements (including the first) in
172 * the configuration. Once an iterator is initiailized with ses_iter_init(),

174 * individual element index via the ses_iter_seek_to() function. You may
175 * also return an iterator to the position just before the first element
