Description: Bound-variable hypothesis builder for operation value, analogous to nfov 6676. To prove a deduction version of this analogous to nfovd 6675 is not quickly possible because many deduction versions for bound-variable hypothesis builder for constructs the definition of alternative operation values is based on are not available (see nfafv 41216).
