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-CO-16. Restoring this fragment makes the complete original invoice pass the selected checks.
[BR-CO-16]-Amount due for payment (BT-115) = Invoice total amount with VAT (BT-112) -Paid amount (BT-113) +Rounding amount (BT-114).Additional triggered rules: 0. None. Counts include distinct error and warning codes; the target code is excluded.
Precise mutated XPath: /*/cac:LegalMonetaryTotal/cbc:PayableAmount.
