What it means
Inside the tax details of the seller's tax representative, EN 16931 only uses the tax scheme identifier, which must be VAT. The rule flags a cac:JurisdictionRegionAddress in the cac:TaxScheme block, an address for the region where the tax scheme applies. UBL allows it, but EN 16931 has no field for it. The check is the same for invoices and credit notes.
Why it matters
EN 16931 does not use a jurisdiction region address in the tax representative's tax scheme.
How to fix it
Remove cac:JurisdictionRegionAddress from cac:TaxRepresentativeParty/cac:PartyTaxScheme/cac:TaxScheme in the exported XML. This is separate from the tax representative's postal address (BG-12), which you do not need to change to clear this warning. Recheck the exported file.
