Proof step 63 from proof validref-putrkvs (previous step)

validref(str, r, ty, st), validval(str, rk, val, st), validvals(str, rkvs0, st), validref(str, r, ty, st[rk, val]) ∧ validvals(str, rkvs0, st[rk, val]) → validref(str, r, ty, st[rk, val][rkvs0]), ∀ str, r, ty, st. validref(str, r, ty, st) ∧ validvals(str, rkvs0, st) → validref(str, r, ty, st[rkvs0]) ⊦ validref(str, r, ty, st[rk, val][rkvs0])
