Proof step 10 from proof validFields-putfis (previous step)

unique_al(fis), sk ∈ fis ∨ sk = sk → r -- sk ∈ st, ∀ sk0. sk0 ∈ fis .keys → r -- sk0 ∈ st ⊦ _length = sk, _type = sk, _length ∈ fis, _type ∈ fis, hasKeys(r, fis .keys, st) ∧ r -- sk ∈ st

And obtained the following new goals

Proof step 9:
unique_al(fis), r -- sk ∈ st, r ∈ st, ∀ sk0. sk0 ∈ fis .keys → r -- sk0 ∈ st ⊦ _length = sk, _type = sk, _length ∈ fis, _type ∈ fis, hasKeys(r, fis .keys, st)
