The rules, on bankofengland.co.uk
How they were counted
Rows in sheet 'capital_plus_sddt' of 'Bank of England Banking Taxonomy Validations Capital Plus for SDDTs v4.1.1.xlsx' (inside the validations ZIP, release 4.1.1) whose 'Severity and modules' column names PRA117. 13 rules: 13 active (Deactivated = no), 13 marked Include in XBRL = yes; 11 errors and 2 warnings. A rule shared by several entry points is counted once for each.
Counts are in the PRA's own unit, so they are not comparable with other regulators' counts.
