How to recognize the profile

Do not rely on the file extension alone. Inspect the root namespace, customization/profile identifiers, version values and authority-specific envelope.

Production validation stack

  1. 1
    XML schema validity

    Confirm that the document is well formed and structurally compatible with the intended EN 16931 syntax.

  2. 2
    EN 16931 Schematron rules

    Apply semantic and business-rule checks rather than accepting a file merely because it parses.

  3. 3
    Code-list validation

    Validate currencies, countries, tax categories, units, payment means and other controlled values against the correct release.

  4. 4
    National CIUS or extension rules

    Apply the national, network or authority restrictions that narrow the base syntax.

EInvoiceLab’s browser tools provide detection, inspection and technical preflight. A profile is only production-valid after applying the correct official artefacts and obtaining the required network or authority outcome.

Questions people ask

What is EN 16931?

The European semantic data model for core electronic invoice business terms. National CIUS profiles and Peppol rules add restrictions on top of the core model.

How is EN 16931 validated?

A production check normally applies XML schema validity, EN 16931 Schematron rules, Code-list validation, National CIUS or extension rules. Local browser preflight cannot replace the official validation artefacts or authority outcome.

Which version should I use?

The current research note is: Validation artefacts maintained independently from the published standard. Confirm release notes at the official source before production deployment.
