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.

Document vocabulary and checks

AT sources support the cited Portuguese invoice-issuance and communicated-invoice particulars and identifiers. Record retention and a complete current certified-software, communication, timing and correction boundary are not yet evidenced here, so this pack remains partial. Special schemes remain transaction-specific checks.
