The SEC announced there will be an EDGAR release on Monday, September 20, 2021. As part of this EDGAR update, they will no longer support the 2019 SEC-IFRS Taxonomy.
Note that the 2019 SEC-IFRS taxonomy includes the 2019 SRT taxonomy which was unsupported on June 21, 2021 (mentioned here), and therefor all filers should be migrated away from the 2019 with this disallowance. Here's a list of of all supported supported standard Taxonomies in EDGAR: https://www.sec.gov/info/edgar/edgartaxonomies.shtml.
Let us know if you have any questions. Cheers!
