Proof step 11 from proof validstatfield-levelsubset (previous step)

tdname∃(str, sk .fs .class), sk ∈ statfields(sk .fs .class), is_fskey(sk), level⊆(str, str0), initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st) ⊦ validstatfield(str0, sk, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 10:
sk = fs ', tdname∃(str, fs .class), sk ∈ statfields(fs .class), is_fskey(sk), level⊆(str, str0), initdone(fs .class, st) → validfield(str, jvmref, sk, st) ⊦ validstatfield(str0, sk, st)

Rule argument
