skynavga has just created a new issue for https://github.com/w3c/imsc:

== Interoperability Goals Not Documented ==
A number of important assumptions as well as features present in IMSC 
are based on interoperability goals that are not documented in the 
specification or elsewhere. Because a reader may not necessarily know 
or share these assumptions, both content and implementations may be 
less interoperable than desired.

This subject should be treated informatively, in introductory material
 (preferably); otherwise, in an appendix.

The following subjects should be addressed:

* whether and how content that conforms to some SMPTE-TT (ST2052) 
profile should be treated by an IMSC compliant processor (of either 
IMSC profile);

* whether and how content that conforms to some EBU-TT profile should 
be treated by an IMSC compliant processor (of either IMSC profile);

* whether and how content that conforms to some TTML1 or SDP-US 
profile should be treated by an IMSC compliant processor (of either 
IMSC profile);

* the converse of the above three subjects

These subjects should be treated from both the perspective of content 
conformance and of processor conformance.
