Feb 1, 2025February 2025 monthly performance for w3c/charter-drafts focused on Timed Text Working Group 2025 charter and related documentation updates. Key work included cross-reference fixes, standardizing RFC2119 case, and updating document statuses/links for IMSC 1.3 and DAPT. Draft content was migrated/ synchronized into the 2025 baseline with updates drawn from charter-timed-text #92 to improve traceability and alignment with WG goals. Resolved clarity and compliance issues by un-capitalizing RFC2119 terms (MUST, SHOULD, SHALL, MAY) and aligning workflow statuses (IMSC 1.3 moved to ED; DAPT WD). These changes strengthen governance, readiness for WG approval, and overall documentation quality. Delivered through a focused set of five commits, ensuring a clean audit trail and easier future maintenance.
