Dear media a11y members of the a11y TF, I think Henry has made a valid observation and we should clarify the boxes that talk about xml. Here's what I suggest changing on the wiki page: For TTML change the box that contains: "The XML root of TTML is seen as a problem by some implementers and authors." to "The XML root of TTML is seen as a problem by some implementers and authors. In particular the use of the XSL-FO formatting model which is not already implemented by browser engines poses a major issue." For WebSRT/WebVTT change the box that contains: ""Is not XML."" to ""Is not XML." In particular it reuses the CSS formatting model rather than XML-based formatting models." Regards, Silvia.
