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:Invoice | /ubl-creditnote:CreditNote)[$supplierCountryIsDE and $customerCountryIsDE]
Test
normalize-space(cbc:InvoiceTypeCode) = $supportedInvAndCNTypeCodes or normalize-space(cbc:CreditNoteTypeCode) = $supportedInvAndCNTypeCodes

Checked with Peppol BIS Billing 3.0 Invoice, Peppol BIS Billing 3.0 Credit Note
