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-50. Restoring this fragment makes the complete original invoice pass the selected checks.
[BR-50]-A Payment account identifier (BT-84) shall be present if Credit transfer (BG-17) information is provided in the Invoice.Additional triggered rules: 1. BR-61. Counts include distinct error and warning codes; the target code is excluded.
Precise mutated XPath: /*/cac:PaymentMeans/cac:PayeeFinancialAccount/cbc:ID.
Before: triggers this rule

After: passes

The context shown is part of a complete invoice; it is not a standalone invoice. Mutation: remove at /*/cac:PaymentMeans/cac:PayeeFinancialAccount/cbc:ID. 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.
