Detected by
tier 2 — XML schema (XSD)
Reachability
Only reachable when validating your own XML — normbill-generated documents cannot trigger it

normbill's serializer emits schema-valid XML by construction; this can only fire for XML submitted to /v1/invoices/validate.

How to fix it

Use one of the allowed values from the validator message. Note that most e-invoice code lists are checked later by Schematron (BR-CL-*), not by the XSD.

cvc-enumeration-valid auf Deutsch — was bedeutet der Fehler?

Der KoSIT-Validator lehnt das Dokument bereits bei der XML-Schema-Prüfung (XSD) ab: Ein Wert gehört nicht zu der festen Werteliste, die das Schema für dieses Element oder Attribut aufzählt.

So beheben Sie den Fehler

Verwenden Sie einen der erlaubten Werte aus der Validator-Meldung. Die meisten E-Rechnungs-Codelisten prüft erst das Schematron (BR-CL-*), nicht das XSD.

Official sources

Every 422 from the API lists the rule id, the path in your request JSON, a plain-language message and a suggested fix — see the docs overview for the report format.

Or try it live: drop any XRechnung XML on the free validator — same KoSIT-backed report, no account.
