DFXP represents a group of folks who are incredibly experienced in all things captioning and description related, including the WGBH NCAM folks who have been working on web solutions for accessible media for years before anyone else was even thinking about these things, I was flummoxed by WebSRT's appearance. Seems incredibly redundant to say the least. So due to politics or whatever, people with hearing loss get to wait while this all gets figured out. The format thing should have gotten worked out at the same time html and got worked out.

Please PLEASE do not start calling WebSRT SRT. Whoever first said "let's base it on SubRip" was onto something good. Now WebSRT is sufficiently different to deserve its own UNIQUE name, or to affix enforcement on the full name WebSRT. In spite of the fact that SubRip's ancient ".SRT" filename extension never passed through any standardization process, its long utility, broad support to this day and broad compatibility, should not be disregarded when naming a new, trans-set or superset format. Please, either always refer to WebSRT in full, or help me campaign for a new, non-conflicting name. It seems like early days for a correction to take root that will please everyone.

It seems very easy, more clear, and useful. A good case is multiple languages for more than one type of track role. For example, you can have one trackgroup for English & Spanish for captions, and another trackgroup for English & Spanish for audio description. I hope “trackgroup” makes it into the spec.

It looks like that standard is close to timed text in it's simplest form. Any idea why it would use xml:id instead of just “id”?
