4252  *   add / delete: all types that may be added or deleted must use an
4253  * X-ORDERED attributeType for their RDN. Adding and deleting entries
4254  * should automatically renumber the index of any siblings as needed,
4255  * so that no gaps in the numbering sequence exist after the add/delete
4256  * is completed.
4257  *   What can be added:
4258  *     schema objects
4259  *     backend objects for backend-specific config directives
4260  *     database objects
4261  *     overlay objects
4262  *
4263  *   delete: probably no support this time around.
4264  *
4265  *   modrdn: generally not done. Will be invoked automatically by add/
4266  * delete to update numbering sequence. Perform as an explicit operation
4267  * so that the renumbering effect may be replicated. Subtree rename must
4268  * be supported, since renumbering a database will affect all its child
4269  * overlays.
4270  *
4271  *  modify: must be fully supported.
