4925  *   add / delete: all types that may be added or deleted must use an
4926  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4927  * should automatically renumber the index of any siblings as needed,
4928  * so that no gaps in the numbering sequence exist after the add/delete
4929  * is completed.
4930  *   What can be added:
4931  *     schema objects
4932  *     backend objects for backend-specific config directives
4933  *     database objects
4934  *     overlay objects
4935  *
4936  *   delete: probably no support this time around.
4937  *
4938  *   modrdn: generally not done. Will be invoked automatically by add/
4939  * delete to update numbering sequence. Perform as an explicit operation
4940  * so that the renumbering effect may be replicated. Subtree rename must
4941  * be supported, since renumbering a database will affect all its child
4942  * overlays.
4943  *
4944  *  modify: must be fully supported.
