The First Public Working Draft of IMSC Text Profile 1.3 has been published!

https://www.w3.org/TR/ttml-imsc1.3/

ICYM, this edition of IMSC:

• adds support for superscript and subscript text
• only defines a text-only profile (an image-only profile remains in older editions of the specification)
• recommends a set of Japanese characters, courtesy of ARIB

The objective is to complete all substantive work before year’s end.
