Proof step 16 from proof validstatfield-level-expand (previous step)

(∀ class. tdname∃(str, class) ∧ initdone(class, st) → validstatfields(str, class, st)) ↔ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validstatfields(str, class, st)) ⊦ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validstatfields(str, class, st)) ↔ (∀ class, sk. tdname∃(str, class) ∧ initdone(class, st) ∧ sk ∈ statfields(class) → validstatfield(str, sk, st))
