Proof step 2 from proof lemma-5-4-2 (previous step)

proj([], Cview(view)) = [], osc(view, trans, eqstate), reachable(trans, s), reachable(trans, s0), eqstate(s, s0), enabled(trans, s, []) ⊦ ∃ tr0. proj(tr0, Cview(view)) = [] ∧ proj(tr0, Vview(view)) = proj([], Vview(view)) ∧ enabled(trans, s0, tr0)
