4273  *   add / delete: all types that may be added or deleted must use an
4274  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4275  * should automatically renumber the index of any siblings as needed,
4276  * so that no gaps in the numbering sequence exist after the add/delete
4277  * is completed.
4278  *   What can be added:
4279  *     schema objects
4280  *     backend objects for backend-specific config directives
4281  *     database objects
4282  *     overlay objects
4283  *
4284  *   delete: probably no support this time around.
4285  *
4286  *   modrdn: generally not done. Will be invoked automatically by add/
4287  * delete to update numbering sequence. Perform as an explicit operation
4288  * so that the renumbering effect may be replicated. Subtree rename must
4289  * be supported, since renumbering a database will affect all its child
4290  * overlays.
4291  *
4292  *  modify: must be fully supported.
