Seller address needs a country code
Seller address needs a country code. The controlled example changes the specific field or group named by this rule. Remove only /*/cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cac:Country/cbc:IdentificationCode.
Business terms: BT-40.
Restore the seller country code from ISO 3166-1.
Reproduced failure and correction
Tested on 2 November 2026 with the production SaxonC-HE 13.1 / saxonche 13.1.1 engine, en16931 mode, UBL. The XSD passes; the report then contains BR-09. Restoring this fragment makes the complete original invoice pass the selected checks.
[BR-09]-The Seller postal address (BG-5) shall contain a Seller country code (BT-40).Additional triggered rules: 0. None. Counts include distinct error and warning codes; the target code is excluded.
Precise mutated XPath: /*/cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cac:Country/cbc:IdentificationCode.
Before: triggers this rule
<cac:Country xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:ubl="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
</cac:Country>
After: passes
<cac:Country xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:ubl="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
<cbc:IdentificationCode>DE</cbc:IdentificationCode>
</cac:Country>
The context shown is part of a complete invoice; it is not a standalone invoice. Mutation: remove at /*/cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cac:Country/cbc:IdentificationCode. The passing baseline is validated with the selected pinned package. UBL examples use a controlled single-line adaptation of the official XRechnung example; the CII example uses the official EN 16931 baseline.

Repair the source data and exporter, then validate the complete invoice again with the same package. Review every remaining error and warning; a passing rule is not a guarantee of recipient acceptance.
