/* Notes:
 *   add / delete: all types that may be added or deleted must use an
 * X-ORDERED attributeType for their RDN. Adding and deleting entries
 * should automatically renumber the index of any siblings as needed,
 * so that no gaps in the numbering sequence exist after the add/delete
 * is completed.
 *   What can be added:
 *     schema objects
 *     backend objects for backend-specific config directives
 *     database objects
 *     overlay objects
 *
 *   delete: probably no support this time around.
 *
 *   modrdn: generally not done. Will be invoked automatically by add/
 * delete to update numbering sequence. Perform as an explicit operation
 * so that the renumbering effect may be replicated. Subtree rename must
 * be supported, since renumbering a database will affect all its child
 * overlays.
 *
 *  modify: must be fully supported.
