In a sibling private package:

private
package P.stuff is

    type Some_Type is ...;
end P.Stuff;

private with P.stuff;
package P is
   protected type PT is
      procedure Foo;
   private
      X : P.Stuff.Some_Type;
   end PT;
end P;

Hmm. Maybe that's not right, since P.Stuff is used in the private part
of a public type, not strictly in the private part of P. But it
_should_ be ok!
