It depends on what you want. I can only guess that you are probably longing
for a sort of generic specialization:
1. A generic child of Jr.Queue
generic
with function ">" (L, R : T) return Boolean is <>;
package Jr.Queue.Ordered is
...
2. A generic package parametrized by an instance of Jr.Queue
generic
type T is private;
with function ">" (L, R : T) return Boolean is <>;
with package Some_Queue is new Jr.Queue (T);
package Ordered_Queue is
...
etc.
