A UBL invoice should not include the PaymentMeans/PayerFinancialAccount
The element 'PaymentMeans/PayerFinancialAccount' is present, but it carries no meaning in the EN 16931 semantic model, so a receiver is free to ignore or reject it.
Remove 'PaymentMeans/PayerFinancialAccount' from the document. Look for //cac:PaymentMeans/cac:PayerFinancialAccount — that is the exact location. Nothing in EN 16931 maps to it - it is almost always left over from a generic UBL template. Reported as a warning.
UBL — context /ubl:Invoice | /cn:CreditNote
not(//cac:PaymentMeans/cac:PayerFinancialAccount)
Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
