The refreshed set includes guidance on iXBRL tagging featureshow to specify mandatory facts for an XBRL report, and how to prepare and publish filing rules, with the latter accompanied by two handy checklists covering XBRL report filing rules and taxonomy extension filing rules. Worth a fresh look for regulators, implementers, and taxonomy designers.
