On March 1, the Securities and Exchange Commission announced a proposed rule that would require the use of Inline XBRL (embedding XBRL data directly into filings, rather than as attachments) and would eliminate the requirement that filers provide XBRL data on their websites. The public comment period on the proposed rule is open until April 30, 2017.

Also on March 1, the SEC published a taxonomy on its website that enables foreign private issuers that prepare their financial statements in accordance with IFRS to submit their financial statements using XBRL. Foreign private issuers may submit their financial statements in XBRL immediately, and, in any case, all foreign private issuers must do so for fiscal periods ending on or after December 15, 2017.

The press releases is available here and here.  The proposing release for Inline XBRL is available here, and the adopting release for the IFRS taxonomy is available here.
