6521 /* Notes:
6522  *   add / delete: all types that may be added or deleted must use an
6523  * X-ORDERED attributeType for their RDN. Adding and deleting entries
6524  * should automatically renumber the index of any siblings as needed,
6525  * so that no gaps in the numbering sequence exist after the add/delete
6526  * is completed.
6527  *   What can be added:
6528  *     schema objects
6529  *     backend objects for backend-specific config directives
6530  *     database objects
6531  *     overlay objects
6532  *
6533  *   delete: probably no support this time around.
6534  *
6535  *   modrdn: generally not done. Will be invoked automatically by add/
6536  * delete to update numbering sequence. Perform as an explicit operation
6537  * so that the renumbering effect may be replicated. Subtree rename must
6538  * be supported, since renumbering a database will affect all its child
6539  * overlays.
6540  *
6541  *  modify: must be fully supported.
