Proof step 13 from proof validstatfields-class-01 (previous step)

initdone(class, st), tdname∃(str, class), sk ∈ statfields(class), validfield(str, jvmref, sk, st) ⊦ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))
