EN 16931 Invoice (CII)

A Cross Industry Invoice checked against the D16B schema and the EN 16931 business rules: the XML inside Factur-X and ZUGFeRD (EN 16931 profile).

About

CII is the second syntax of EN 16931. The rules are the same business rules as for UBL, bound to CII elements, plus the code list checks the uncoupled D16B schema leaves out.

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

  • Rules run only when the document matches the schema. Documents over 50 MB are checked against the schema only.
  • The example is from the EN 16931 validation artefacts by the European Commission (EUPL 1.2).

The validator loads all of these with their folder structure, so includes and imports resolve as published.

Business rules

Schematron · run in this order

The rules run after the schema check, only when the document matches the schema, and in your browser like the schema check (with SaxonJS by Saxonica). Each finding names its rule, such as BR-CO-15, and the line it points at; each rule has a page with what it checks.
