XBRL is one way to make a return machine-readable; a check at the gate is what turns it into supervision. Read how XBRL validation works and the path to real-time supervision.
XBRL formats as each regulator's own pages describe them. Not legal or regulatory advice: always rely on the regulator's own text. Not affiliated with or endorsed by any regulator.
