Proof step 58 from proof validfieldinits-def-01 (previous step)

∀ str, st. validfieldinits(str, fis0, st) ↔ validfieldinits(fis0, st) ∧ ¬ junkrefs(str, fis0 .vals, st) ∧ (∀ sk. sk ∈ fis0 → type∃(str, sk .fs .type)) ⊦ validfieldinits(str, fv + fis0, st) ↔ validfieldinits(fv + fis0, st) ∧ ¬ junkrefs(str, (fv + fis0) .vals, st) ∧ (∀ sk. sk ∈ fv + fis0 → type∃(str, sk .fs .type))
