my instansiation of a generic Remote_Call_Interface need a type declared in a package of wrong categorization

[dontspam365@gmail.com]

Hi!

I have created the following test packages for my question: My_RCI and Test_RCI(generic).
I am trying to create a distributed application. I would like to make several of these packages generic.

In some cases I run into the issue, that I wish to instantiate a Remote_Call_Interface package.
Below I have My_RCI. This package tries to instantiate the necessary packages. However, the __body__ of Test_RCI need a type that is declared in Core_Package. Core_Package is not of correct categorization (and I can't make it become so).
The specification part of Test_RCI and My_RCI are not depending on Core_Package.
As soon as I "with" the Core_Package I get error message of course.
Does it exists some method to "trinkle" Core_Package through to the body of Test_RCI? I have tried quite a few things to solve this, and I have at the moment given up:)

with Core_Package; --  <- not good :)
with Test_RCI;

package My_RCI is
   pragma Remote_Call_Interface;

   package This is new test_rci  (Core_package.Useful_Type);

   procedure Some_Call;
end My_RCI;

package body My_RCI is

   procedure Some_Call
   is
   begin
      null;
   end Some_Call;
end My_RCI;


generic
   type Some_Type is range <>;
package Test_RCI is
  pragma Remote_Call_Interface;

  procedure Test_RCI;

end Test_RCI;


package body Test_RCI is

   procedure Test_RCI
   is
      A_Variable : Some_Type;
   begin
      A_Variable := 1;
   end Test_RCI;

end Test_RCI;
