Validation rules
The NBB publishes the checks it runs on this return. They could not be counted from the published material. They are written for people to read; software cannot run them as published. Source
How they are written: Excel rules file linked on the MBS XML page (not read).
How they were counted
Not counted: the rules file phl2024.xlsx could not be read (robots.txt disallows .xlsx).
Counts are in the NBB's own unit, so they are not comparable with other regulators' counts.
Public data
No published data from this return was found. No data from this return published by the NBB was found on the pages checked. Source
