nigelmegitt has just created a new issue for https://github.com/w3c/ttml2:

== Profile related features should be optional ==
In the transformation and processor profiles, the following feature designators should be marked as optional rather than required:

* `#contentProfiles`
* `#inferProcessorProfile`
* `#permitFeatureNarrowing`
* `#permitFeatureWidening`
* `#profile-version-2`

Rationale: It is reasonable for processors to support TTML2 in processing contexts where profile processing is not required and to omit support for those features.
