Axiom ax-cnex

Description: The complex numbers form a set. This axiom is redundant - see cnexALT - but we provide this axiom because the justification theorem axcnex does not use ax-rep even though the redundancy proof does. Proofs should normally use cnex instead. (New usage is discouraged.) (Contributed by NM, 1-Mar-1995)
