Public Exposure of Validation Rules & Guidance

Public review and comment is a critical part of the process of improving the usability of XBRL filed with the SEC. Generally, rules are considered for approval within 45 days of the close of public exposure for comment, and should be implemented in all filings within 90 days of approval.

During the Public Review period for version 31 the Data Quality Committee sought comment on five automated checks for US GAAP filers, as well as updates to previously approved rules for filers using the US GAAP and IFRS taxonomies, from Saturday, August 15 through Wednesday, September 30, 2026.

The latest compiled rule releases and reference implementation code are linked at right. These resources can be used with Arelle - the free, open source XBRL processor - and the XULE rules engine. See the schedule in the inset box for approximate public exposure period timing.
