Why these defaults?
The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.
Recorded official or regional-official language tags: fr.
Source review completed; detailed guidance unavailable
Evidence is insufficient for safe claim-level guidance
No authority source captured resolving VAT exclusion/local transaction document rules. This is a documented research blocker, not a conclusion that no requirements exist. No parent-country rules are inherited and no compliance claim is made.
