Discussion
This property corresponds to the co key of the Unicode BCP 47 extension.
For locale instances created with the co specifier (such as en-US@co=phonetic), or with a custom Locale.Components, this property represents the custom collation. Otherwise, it represents the locale’s default sort order.
