5893  *   add / delete: all types that may be added or deleted must use an
5894  * X-ORDERED attributeType for their RDN. Adding and deleting entries
5895  * should automatically renumber the index of any siblings as needed,
5896  * so that no gaps in the numbering sequence exist after the add/delete
5897  * is completed.
5898  *   What can be added:
5899  *     schema objects
5900  *     backend objects for backend-specific config directives
5901  *     database objects
5902  *     overlay objects
5903  *
5904  *   delete: probably no support this time around.
5905  *
5906  *   modrdn: generally not done. Will be invoked automatically by add/
5907  * delete to update numbering sequence. Perform as an explicit operation
5908  * so that the renumbering effect may be replicated. Subtree rename must
5909  * be supported, since renumbering a database will affect all its child
5910  * overlays.
5911  *
5912  *  modify: must be fully supported.
