Theorem rdgifnon 6432

Description: The recursive definition generator is a function on ordinal numbers. The F Fn _V condition states that the characteristic function is defined for all sets (being defined for all ordinals might be enough if being used in a manner similar to rdgon 6439; in cases like df-oadd 6473 either presumably could work).
