5896  *   add / delete: all types that may be added or deleted must use an
5897  * X-ORDERED attributeType for their RDN. Adding and deleting entries
5898  * should automatically renumber the index of any siblings as needed,
5899  * so that no gaps in the numbering sequence exist after the add/delete
5900  * is completed.
5901  *   What can be added:
5902  *     schema objects
5903  *     backend objects for backend-specific config directives
5904  *     database objects
5905  *     overlay objects
5906  *
5907  *   delete: probably no support this time around.
5908  *
5909  *   modrdn: generally not done. Will be invoked automatically by add/
5910  * delete to update numbering sequence. Perform as an explicit operation
5911  * so that the renumbering effect may be replicated. Subtree rename must
5912  * be supported, since renumbering a database will affect all its child
5913  * overlays.
5914  *
5915  *  modify: must be fully supported.
