+(** This file extends ClassicalDescription.v with the axiom of choice.
+    As ClassicalDescription.v, it implies the double-negation of
+    excluded-middle in Set and implies a strongly classical
+    world. Especially it conflicts with impredicativity of Set, knowing
+    that true<>false in Set.

+Theorem choice : 
+ (A:Type;B:Type;R: A->B->Prop)
+  ((x:A)(EX y:B|(R x y))) -> (EX f:A->B | (x:A)(R x (f x))).
+Proof.
+Apply description_rel_choice_imp_funct_choice.
+Exact description.
+Exact relational_choice.
+Qed.
