5901  *   add / delete: all types that may be added or deleted must use an
5902  * X-ORDERED attributeType for their RDN. Adding and deleting entries
5903  * should automatically renumber the index of any siblings as needed,
5904  * so that no gaps in the numbering sequence exist after the add/delete
5905  * is completed.
5906  *   What can be added:
5907  *     schema objects
5908  *     backend objects for backend-specific config directives
5909  *     database objects
5910  *     overlay objects
5911  *
5912  *   delete: probably no support this time around.
5913  *
5914  *   modrdn: generally not done. Will be invoked automatically by add/
5915  * delete to update numbering sequence. Perform as an explicit operation
5916  * so that the renumbering effect may be replicated. Subtree rename must
5917  * be supported, since renumbering a database will affect all its child
5918  * overlays.
5919  *
5920  *  modify: must be fully supported.
