Implementation Advice
{
AI95-00395-01}
If an implementation chooses to provide implementation-defined operations
on Wide_Character or Wide_String (such as case mapping, classification,
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.
