You don't need an access type for this (in Ada, you rarely need access
types at all). You can simply operate on the String returned by
To_String:

declare
   Value : [constant] String := To_String (Unbounded_Value);
begin
   -- Operate with/on Value
   Unbounded_Value := To_Unbounded_String (Value); -- if needed
end;
