6216  *   add / delete: all types that may be added or deleted must use an
6217  * X-ORDERED attributeType for their RDN. Adding and deleting entries
6218  * should automatically renumber the index of any siblings as needed,
6219  * so that no gaps in the numbering sequence exist after the add/delete
6220  * is completed.
6221  *   What can be added:
6222  *     schema objects
6223  *     backend objects for backend-specific config directives
6224  *     database objects
6225  *     overlay objects
6226  *
6227  *   delete: probably no support this time around.
6228  *
6229  *   modrdn: generally not done. Will be invoked automatically by add/
6230  * delete to update numbering sequence. Perform as an explicit operation
6231  * so that the renumbering effect may be replicated. Subtree rename must
6232  * be supported, since renumbering a database will affect all its child
6233  * overlays.
6234  *
6235  *  modify: must be fully supported.
