About

This is the D16B subset with uncoupled code lists that the European Commission publishes with the EN 16931 validation artefacts. Code values are checked by the Schematron rules there, not by the schema.

To check a Factur-X or ZUGFeRD invoice, extract the embedded factur-x.xml or zugferd-invoice.xml from the PDF first.

Good to know

  • This entry checks the schema only. For the business rules, choose the EN 16931 (CII), XRechnung (CII), Factur-X or French CII entry.
  • The example is from the EN 16931 validation artefacts by the European Commission (EUPL 1.2).
