> A Danish payment reminder (rykker) in OIOUBL 2.1, checked against the UBL 2.1 Reminder schema and the OIOUBL Schematron.

A reminder (rykker) tells the buyer that an invoice is overdue, with any fee or interest. OIOUBL sends it as the UBL Reminder document, through NemHandel like invoices.

## Notes

- Rules run only when the document matches the schema. Documents over 50 MB are checked against the schema only.
- The rules are NemHandel's OIOUBL Schematron 1.17.2; the rule ids and levels (F- errors, W- warnings) are the ones their messages name.
- The example is from the test files of the OIOUBL Schematron package, as phive-rules keeps them.
