32 -- This non generic package contains most of the implementation of the
33 -- generic package Ada.Strings.Wide_Bounded.Generic_Bounded_Length.
35 -- It defines type Super_String as a discriminated record with the maximum
36 -- length as the discriminant. Individual instantiations of the package
37 -- Strings.Wide_Bounded.Generic_Bounded_Length use this type with
38 -- an appropriate discriminant value set.

56 -- they can be renamed in Ada.Strings.Wide_Bounded.Generic_Bounded_Length.
