TimedText/DAPT Implementation Report

Features

DAPT-specific features

Most features of DAPT are already tested as part of the TTML 2 implementation report. The additional features are listed here, alongside their relevant tests and implementations that pass those tests.

Tests whose names begin dapt-invld- include resources that a passing validation implementation declares to be invalid.

Tests whose names begin dapt-valid- include resources that a passing validation implementation declares to be valid.

TODO: Add additional implementations

DAPT At-risk features

Some TTML2 features are included in DAPT but marked as "at risk", meaning that any that do not meet the TTWG's inclusion criteria, most likely that they are supported in at least two implementations, will be removed from the specification before it advances to Recommendation. Therefore, we are interested to log any implementations that do support them.
