code: @API(status = INTERNAL)
      public static <A> Binding<A> create(@Nullable final A attribute, final Route route) {
          return new Binding<>(attribute, route);
      }
docs: A static factory to create bindings. {@link Bindings#on(Object)} and {@link PartialBinding} provide the same
  functionality but with some more syntactic sugar.
