one i18n discussion took longer than group expected, so WG resolved to request transition once the discussion settled.

# Issues status
https://github.com/w3c/dapt/issues

Some at-risk features are listed in issues, most at-risk points are assumed to stand at the final REC. 
(Per [Process for CRD to REC AC review](https://www.w3.org/policies/process/20250818/#transition-rec-requirements), dropping at-risk is allowed but removing at-risk label seems not allowed. So, another CRS request would come?)

# Formal Objections
no

# Any changes in implementation information?
[Implementation report](https://www.w3.org/wiki/TimedText/DAPT_Implementation_Report) is under development.

# Deadline for further comments
28 days after publication (as standard)

# Any changes in patent disclosures?
[None](https://www.w3.org/groups/wg/timed-text/ipr/#current-disclosures)
