The document must not contain empty elements.
- Rule
PEPPOL-EN16931-R008— official EN 16931 / XRechnung rule- Severity
- error
- Detected by
- tier 3 — KoSIT validator (authoritative)
- Reachability
- Only reachable when validating your own XML — normbill-generated documents cannot trigger it
The request schema requires non-empty strings and the serializer omits absent fields, so generated documents never contain empty elements.
How to fix it
Remove empty XML elements — an absent field is expressed by omitting its element entirely.

Das Dokument darf keine leeren XML-Elemente enthalten.
So beheben Sie den Fehler
