Proof step 20 from proof validstatfields-subset (previous step)

init(str, st0), init(str, st), st ⊆ st0, validstatfields(str, st) ⊦ ∀ class, sk. tdname∃(str, class) ∧ initdone(class, st0) ∧ sk ∈ statfields(class) → validstatfield(str, sk, st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
validstatfields(str, st), st ⊆ st0, init(str, st), init(str, st0), sk ∈ statfields(class), initdone(class, st0), tdname∃(str, class) ⊦ validstatfield(str, sk, st0)
