Validation rules

The CNB publishes the checks it runs on this return. They could not be counted from the published material. Software can run them exactly as published. Source

How they are written: EBA validation rules in the EBA reporting framework (see the EBA entry); SDAT taxonomy checks.

Counts are in the CNB's own unit, so they are not comparable with other regulators' counts.
