4250  *   add / delete: all types that may be added or deleted must use an
4251  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4252  * should automatically renumber the index of any siblings as needed,
4253  * so that no gaps in the numbering sequence exist after the add/delete
4254  * is completed.
4255  *   What can be added:
4256  *     schema objects
4257  *     backend objects for backend-specific config directives
4258  *     database objects
4259  *     overlay objects
4260  *
4261  *   delete: probably no support this time around.
4262  *
4263  *   modrdn: generally not done. Will be invoked automatically by add/
4264  * delete to update numbering sequence. Perform as an explicit operation
4265  * so that the renumbering effect may be replicated. Subtree rename must
4266  * be supported, since renumbering a database will affect all its child
4267  * overlays.
4268  *
4269  *  modify: must be fully supported.
