4281  *   add / delete: all types that may be added or deleted must use an
4282  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4283  * should automatically renumber the index of any siblings as needed,
4284  * so that no gaps in the numbering sequence exist after the add/delete
4285  * is completed.
4286  *   What can be added:
4287  *     schema objects
4288  *     backend objects for backend-specific config directives
4289  *     database objects
4290  *     overlay objects
4291  *
4292  *   delete: probably no support this time around.
4293  *
4294  *   modrdn: generally not done. Will be invoked automatically by add/
4295  * delete to update numbering sequence. Perform as an explicit operation
4296  * so that the renumbering effect may be replicated. Subtree rename must
4297  * be supported, since renumbering a database will affect all its child
4298  * overlays.
4299  *
4300  *  modify: must be fully supported.
