Committed, thank you.
There are a few things I don't understand that would be good to
document better:
* Rules. I still don't quite understand the use case: are these for
people inventing new languages? What is a plausible use case that isn't
covered by the existing locales and collation settings? Do rules make
sense for a database default collation? Are they for language experts
only or might an ordinary developer benefit from using them?
* The collation types "phonebk", "emoji", etc.: are these variants of
particular locales, or do they make sense in multiple locales? I don't
know where they fit in or how to document them.
* I don't understand what "kc" means if "ks" is not set to "level1".
Regards,
Jeff Davis
