7226  *   add / delete: all types that may be added or deleted must use an
7227  * X-ORDERED attributeType for their RDN. Adding and deleting entries
7228  * should automatically renumber the index of any siblings as needed,
7229  * so that no gaps in the numbering sequence exist after the add/delete
7230  * is completed.
7231  *   What can be added:
7232  *     schema objects
7233  *     backend objects for backend-specific config directives
7234  *     database objects
7235  *     overlay objects
7236  *
7237  *   delete: probably no support this time around.
7238  *
7239  *   modrdn: generally not done. Will be invoked automatically by add/
7240  * delete to update numbering sequence. Perform as an explicit operation
7241  * so that the renumbering effect may be replicated. Subtree rename must
7242  * be supported, since renumbering a database will affect all its child
7243  * overlays.
7244  *
7245  *  modify: must be fully supported.
