The first sentence reads:
"The set of languages, calendars, and countries that are supported in  
the date formatting functions is implementation-defined."

"Implementation-defined" is a fancy way of saying "the committee  
couldn't agree on a realistic interoperable solution".

Good luck researching country-specific Julian/Gregorian roll-over  
dates and new year rules. The current country codes don't cover for  
example Venice adopting the modern new year rule at a different time  
than Rome.

And good luck supporting calendars that even ICU doesn't know about.

Non-Gregorian calendars are a huge can of worms. Let's put the lid  
back on right away.
