Don't duplicate. Not here. Not needed. Make distinct packages HTTP.Headers,=
 HTTP.Request_Messages, etc. Top package HTTP may have common things e.g. a=
 root type for messages, or may be empty; HTTP.Request_Messages uses (withe=
ns) HTTP.Headers; you can make a type T1 with public and private fields eas=
ily using type extension(maybe there are other ways):

   type T0 is tagged
      record
         <public fields>
      end record;

   type T1 is new T0 with private;
private
   type T1 is new T0 with
      record
         <private fields>
      end record;
