Theorem axsep 5193
Description: Axiom scheme of separation ax-sep 5194 derived from the axiom scheme of replacement ax-rep 5181. The statement is identical to that of ax-sep 5194, and therefore shows that ax-sep 5194 is redundant when ax-rep 5181 is allowed. See ax-sep 5194 for more information. (Contributed by NM, 11-Sep-2006.) Use ax-sep 5194 instead. (New usage is discouraged.)
