Document format and locale facts for Spain

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: es, ca, gl, eu, ast, oc.
