proposition: Lemma valid_package_inject_import : ∀ L I1 I2 E p, fsubset I1 I2 → ValidPackage L I1 E p → ValidPackage L I2 E p.
proof: Proof. intros L I1 I2 E p hE h. apply prove_valid_package. eapply from_valid_package in h. intros [n [S T]] ho. specialize (h _ ho). cbn in h. destruct h as [f [ef hf]]. exists f. intuition auto. eapply valid_injectMap. all: eauto. Qed.
