5902  *   add / delete: all types that may be added or deleted must use an
5903  * X-ORDERED attributeType for their RDN. Adding and deleting entries
5904  * should automatically renumber the index of any siblings as needed,
5905  * so that no gaps in the numbering sequence exist after the add/delete
5906  * is completed.
5907  *   What can be added:
5908  *     schema objects
5909  *     backend objects for backend-specific config directives
5910  *     database objects
5911  *     overlay objects
5912  *
5913  *   delete: probably no support this time around.
5914  *
5915  *   modrdn: generally not done. Will be invoked automatically by add/
5916  * delete to update numbering sequence. Perform as an explicit operation
5917  * so that the renumbering effect may be replicated. Subtree rename must
5918  * be supported, since renumbering a database will affect all its child
5919  * overlays.
5920  *
5921  *  modify: must be fully supported.
