Where the list was read: Source

Validation rules

The BdE 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: PDF of cross-checks ('Correlaciones').

Under I.E. 2008.02, statements that fail the validations are, as a general rule, rejected automatically and treated as not filed; part of the checks are also published in XBRL in the Bank's taxonomies.

The rules, on bde.es

How they were counted

Not counted: '6341_CF1_FIN.pdf' is a PDF in an older layout whose rules could not be counted reliably from its text.

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