## Notes

- Rules run only when the document matches the schema. Documents over 50 MB are checked against the schema only.
- Rule levels follow the KoSIT validator configuration (2026-08-31) for the scenario the document declares (XRechnung, Extension or CVD): a few code list rules are warnings there, a few line rules errors. Its "information" level is shown as a warning.
- The example is from the XRechnung test suite by KoSIT (Apache License 2.0).
