skynavga has just created a new issue for https://github.com/w3c/imsc: == Potential semantic conflict between ttp:profile and ttp:contentProfiles. == At present, neither IMSC1.2 nor TTML2 says anything about the case where a document requires a processor to support one profile but declares the document to conform to another profile that is mutually exclusive with the former. Since TTML2 doesn't define mutually exclusive profiles, TTML2 has not had the need to say anything of note in this regard, but it would possibly seem relevant for IMSC1.2 to do so given the mutual exclusivity of its text and image profiles. For example, it would be a bit strange for a document to specify ``` <tt xmlns="http://www.w3.org/ns/ttml" xmlns:ttp="http://www.w3.org/ns/ttml#parameter" ttp:profile="http://www.w3.org/ns/ttml/profile/imsc1.1/text" ttp:contentProfiles="http://www.w3.org/ns/ttml/profile/imsc1.1/image"> ... </tt> ``` However, AFAICT, this is a perfectly legitimate IMSC1.X document.
