BR-06: Seller name is required

Seller name is required; restore the seller legal name in RegistrationName.

What the rule says

[BR-06]-An Invoice shall contain the Seller name (BT-27).

Official en16931 source, version 1.3.16. EUPL 1.2; sources, licences and notices. Syntax and business checks are separate; this is not certification.

Seller name is required

Seller name is required. The controlled example changes the specific field or group named by this rule. Remove only /*/cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName.

Business terms: BT-27.

Restore the seller legal name in RegistrationName.

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-06. Restoring this fragment makes the complete original invoice pass the selected checks.

[BR-06]-An Invoice shall contain the Seller name (BT-27).

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:PartyLegalEntity/cbc:RegistrationName.

Before: triggers this rule

<cac:PartyLegalEntity 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:CompanyID>[HRA-Eintrag]</cbc:CompanyID>
                <cbc:CompanyLegalForm>123/456/7890, HRA-Eintrag in [&#8230;]</cbc:CompanyLegalForm>
            </cac:PartyLegalEntity>

After: passes

<cac:PartyLegalEntity 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:RegistrationName>[Seller name]</cbc:RegistrationName>
                <cbc:CompanyID>[HRA-Eintrag]</cbc:CompanyID>
                <cbc:CompanyLegalForm>123/456/7890, HRA-Eintrag in [&#8230;]</cbc:CompanyLegalForm>
            </cac:PartyLegalEntity>

The context shown is part of a complete invoice; it is not a standalone invoice. Mutation: remove at /*/cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName. 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.
