There was a problem hiding this comment.
This section concerns signaling of IMSC documents, not DAPT document that happen to also conform to IMSC, which, in any case does not require the use of ttp:contentProfiles. This section should be moved to the dapt-interop appendix.

@nigelmegitt Do you want to edit this directly, or would you rather do so? Does this also close #524? |

I'll take a swing at this.
Good question. Unclear, I think, because the requirements on presentation implementations are undefined. |
* Explain use of multiple values in `ttp:contentProfiles` * Add DAPT to the list of compatible specifications in the overview * Add a DAPT interoperability section to appendix I including constraints and compatibility notes * Describe how DAPT metadata can be used in an IMSC context
so it can be used in DAPT
Allows Respec to find links to things defined in DAPT even if they've not been exported yet.

Closes #622
ttp:contentProfilesCan be improved later to use definitions exported from DAPT, but directly cites non-exported definitions for the time being.
