Initial description deprecated after USG agreed to modifications:
-STIX v2.1 was published without USG copyright notice as originally agreed.
Corrections: Republish with "Portions copyright © United States Government 2012-2021. All Rights Reserved." added to front page Notices section right after OASIS copyright.-
Make changes per attached file : stix-v2.1-os-FORENSIC-jbc2022.docx
Changes appear to consist of removing all the STIX and TAXII TM markings, adding a bolus of USG copyright info to the Notices sections, and setting the copyright year to 2022.
