Sadly, neither of those means a whole lot to me? :-(

How did you find out that those are equivalent?

See, I'm confused, because that link says "If a keyword list is
present it must be preceded by an at-sign" which makes it sound like
it is talking about stuff like en_US(at)colstrength=primary rather than
stuff like en-US-u-ks-level1. The examples are all that way too, like
it gives examples like en_IE(at)currency=IEP and
fr(at)collation=phonebook;calendar=islamic-civil.
