Proof step 22 from proof ac-refin (previous step)

rk ∈ st, is_fskey(fv .1), ∀ rk, st, class. rk ∈ st → rk ∈ addclass(class, fis0, st) ⊦ fv .1 .fs .class = class, rk ∈ addclass(class, fis0, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 21:
fv = sk × val, rk ∈ st, is_fskey(sk), ∀ rk, st, class. rk ∈ st → rk ∈ addclass(class, fis0, st) ⊦ sk .fs .class = class, rk ∈ addclass(class, fis0, st)
