6218  *   add / delete: all types that may be added or deleted must use an
6219  * X-ORDERED attributeType for their RDN. Adding and deleting entries
6220  * should automatically renumber the index of any siblings as needed,
6221  * so that no gaps in the numbering sequence exist after the add/delete
6222  * is completed.
6223  *   What can be added:
6224  *     schema objects
6225  *     backend objects for backend-specific config directives
6226  *     database objects
6227  *     overlay objects
6228  *
6229  *   delete: probably no support this time around.
6230  *
6231  *   modrdn: generally not done. Will be invoked automatically by add/
6232  * delete to update numbering sequence. Perform as an explicit operation
6233  * so that the renumbering effect may be replicated. Subtree rename must
6234  * be supported, since renumbering a database will affect all its child
6235  * overlays.
6236  *
