Fixture ID: regionalNoSellerId · XPath: N/A (Computed / Semantic Rule)
A line uses VAT category L (Canary Islands general indirect tax (IGIC)), so the invoice must carry the seller VAT identifier (BT-31), the seller tax registration identifier (BT-32), or a seller tax representative (BG-11). IGIC is the Canary Islands' own indirect tax, charged instead of VAT because the archipelago sits outside the EU VAT area. It is still a tax you collect on the state's behalf, so the state still has to be able to trace it to a registered person.
BR-AF-02Set seller.vatId (e.g. "DE123456789"). If you are not VAT-registered but have a national tax number, set seller.taxRegistrationId instead.
