I had a look at this spec yesterday. My first thought is that this
does not really affect SVG much: the implementations are in Flash, and
Silverlight, and in some special-purpose clients. Compare

  http://caniuse.com/#search=ttml
and
 http://caniuse.com/#feat=webvtt

TTML is a bit odd, in modern terms; it uses like a dozen XML
namesopaces and has its own special styling language. For captioning
in web-oriented video, WebVTT looks like a more useful spec.

I checked and there are no mentions of SVG. The image captioning
profile is a bunch of PNG images with alt text for accessibility.

On the other hand if the broadcast industry is getting use out of it,
good for them.

In summary, my review comments would be "thanks for asking, we have no
review comments".
