What the rule checks

As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.

Context
/ubl:Invoice | /cn:CreditNote
Test
(((cbc:InvoiceTypeCode | cbc:CreditNoteTypeCode) = "381" or (cbc:InvoiceTypeCode | cbc:CreditNoteTypeCode) = "81") and (((cac:BillingReference) and (cac:DiscrepancyResponse/cbc:ResponseCode != "VD")) or (not(cac:BillingReference) and (cac:DiscrepancyResponse/cbc:ResponseCode = "VD")))) or not((cbc:InvoiceTypeCode | cbc:CreditNoteTypeCode) = "381" or (cbc:InvoiceTypeCode | cbc:CreditNoteTypeCode) = "81")
