Hi Nigel,

Below are a couple of IMSCvNEXT-related topics:

- FPWD of IMSCvNEXT
- liaison to external organizations re: IMSCvNEXT
- questions raised by Mike Dolan
(https://lists.w3.org/Archives/Public/public-tt/2017Oct/0023.html)
    - deprecation of IMSC1 features such as smpte:backgoundImage
    - replacing references from TTML1 to TTML2

Best,

-- Pierre
