Implementation Advice
{

{
AI05-0185-1}
If an implementation chooses to provide implementation-defined operations
on Wide_Character or Wide_String (such as collating and sorting, etc.)
it should do so by providing child units of Wide_Characters. Similarly
if it chooses to provide implementation-defined operations on Wide_Wide_Character
or Wide_Wide_String it should do so by providing child units of Wide_Wide_Characters.
Implementation Advice: Implementation-defined
operations on Wide_Character, Wide_String, Wide_Wide_Character, and Wide_Wide_String
should be child units of Wide_Characters or Wide_Wide_Characters.
