Subject: How to access Vector.Index_Type?

I have the following program 

    with Ada.Containers.Vectors;

    procedure Test is
        package MyVec is new Ada.Containers.Vectors(Natural, Natural);
        Var : MyVec.Index_Type;
    begin
        null;
    end;

I get the following error:  
"Index_Type" is not a visible entity of "MyVec"  

How can I access the index type (`Element_Type` gives the same error message), without just writing `Natural`?
