> The technical acknowledgement of a Peppol message: accepted, or rejected with the failed rules.

A Message Level Response tells the sender whether a received business document passed validation. Two layers are checked: the UBL 2.1 Application Response schema and the Peppol rules.

- Type: XSD + Schematron
- Version: 3.0
- Namespace: `urn:oasis:names:specification:ubl:schema:xsd:ApplicationResponse-2`
- Root element: `ApplicationResponse`
- Publisher: OpenPeppol (OASIS copyright notice), source: https://docs.peppol.eu/poacc/upgrade-3/syntax/MLR/tree/
- Rules: [Peppol Message Level Response rules 3.0](https://xmlvalid.com/rules/sets/peppol-mlr)
- Validate against it: https://xmlvalid.com/validate?schema=peppol-mlr

## Notes

- Rules run only when the document matches the schema.
- The rules and the example are published by OpenPeppol in the BIS upgrade-3 package.
