fatalEN 16931syntax binding ruleUBL
Seller tax representative VAT identifier shall occur maximum once, if the Seller has a tax representative
The Seller tax representative VAT identifier (BT-63) appears more than once. The Seller tax representative (BG-11) is a single party, so each of its details has one value.
Keep one Seller tax representative VAT identifier (BT-63) and delete the rest. A seller with representatives in several countries names the one representing them for this supply.

Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
