Proof step 12 from proof validstatfields-subset (previous step)

sk = fs ' ∧ is_fskey(sk), fs = mkfs(class0, ty, fieldvar), st ⊆ st0, init(str, st), init(str, st0), sk ∈ statfields(class), initdone(class, st0), tdname∃(str, class), initdone(class, st) → validstatfield(str, sk, st) ⊦ validstatfield(str, sk, st0), validstatfield(str, sk, st) ∧ initdone(class0, st0) ∧ initdone(class0, st)

Proof step 11:
