"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.
