7242  *   add / delete: all types that may be added or deleted must use an
7243  * X-ORDERED attributeType for their RDN. Adding and deleting entries
7244  * should automatically renumber the index of any siblings as needed,
7245  * so that no gaps in the numbering sequence exist after the add/delete
7246  * is completed.
7247  *   What can be added:
7248  *     schema objects
7249  *     backend objects for backend-specific config directives
7250  *     database objects
7251  *     overlay objects
7252  *
7253  *   delete: probably no support this time around.
7254  *
7255  *   modrdn: generally not done. Will be invoked automatically by add/
7256  * delete to update numbering sequence. Perform as an explicit operation
7257  * so that the renumbering effect may be replicated. Subtree rename must
7258  * be supported, since renumbering a database will affect all its child
7259  * overlays.
