== Refactor #profile-version-2 feature (#687). ==
Closes #687.

In addition to resolving the specific issue noted in #687, this PR updates the definition of ``#profile`` to employ a [new formulaic approach](https://github.com/w3c/ttml2/issues/697#issuecomment-389329564) to (re)defining features inherited from TTML1.
