-- Different languages use different schemes for ordinals, and some of these schemes are shared between languages.
"SchemeFromLang" picks an ordinal scheme based on a specified language.
All unlisted languages default to the "period-scheme", i.e. "104." is the ordinal for the value "104".
Languages will follow the regular language fallback chain. For example, "de-formal" would fallback to scheme for "de",
and only if that does not exist would the "period-scheme" be used.
