4583 /* Notes:
4584  *   add / delete: all types that may be added or deleted must use an
4585  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4586  * should automatically renumber the index of any siblings as needed,
4587  * so that no gaps in the numbering sequence exist after the add/delete
4588  * is completed.
4589  *   What can be added:
4590  *     schema objects
4591  *     backend objects for backend-specific config directives
4592  *     database objects
4593  *     overlay objects
4594  *
4595  *   delete: probably no support this time around.
4596  *
4597  *   modrdn: generally not done. Will be invoked automatically by add/
4598  * delete to update numbering sequence. Perform as an explicit operation
4599  * so that the renumbering effect may be replicated. Subtree rename must
4600  * be supported, since renumbering a database will affect all its child
4601  * overlays.
4602  *
4603  *  modify: must be fully supported.
