5261  *   add / delete: all types that may be added or deleted must use an
5262  * X-ORDERED attributeType for their RDN. Adding and deleting entries
5263  * should automatically renumber the index of any siblings as needed,
5264  * so that no gaps in the numbering sequence exist after the add/delete
5265  * is completed.
5266  *   What can be added:
5267  *     schema objects
5268  *     backend objects for backend-specific config directives
5269  *     database objects
5270  *     overlay objects
5271  *
5272  *   delete: probably no support this time around.
5273  *
5274  *   modrdn: generally not done. Will be invoked automatically by add/
5275  * delete to update numbering sequence. Perform as an explicit operation
5276  * so that the renumbering effect may be replicated. Subtree rename must
5277  * be supported, since renumbering a database will affect all its child
5278  * overlays.
5279  *
5280  *  modify: must be fully supported.
