5891  *   add / delete: all types that may be added or deleted must use an
5892  * X-ORDERED attributeType for their RDN. Adding and deleting entries
5893  * should automatically renumber the index of any siblings as needed,
5894  * so that no gaps in the numbering sequence exist after the add/delete
5895  * is completed.
5896  *   What can be added:
5897  *     schema objects
5898  *     backend objects for backend-specific config directives
5899  *     database objects
5900  *     overlay objects
5901  *
5902  *   delete: probably no support this time around.
5903  *
5904  *   modrdn: generally not done. Will be invoked automatically by add/
5905  * delete to update numbering sequence. Perform as an explicit operation
5906  * so that the renumbering effect may be replicated. Subtree rename must
5907  * be supported, since renumbering a database will affect all its child
5908  * overlays.
5909  *
5910  *  modify: must be fully supported.
