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: ESMA XML schema (RTS 22) plus field-level guidelines.

ESMA's FIRDS reference-data registers are also used as external code lists in the checks.

How they were counted

Not counted here: ESMA publishes the XML schema and guidelines for MiFIR transaction reporting directly.

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

Public data
