Hi Pierre, Thanks for making these edits. I've reviewed them and have some feedback below on the changes for the comments which I don't think have been fully addressed; the other referenced comments look like they've been addressed, to me: LC-2977: the edit doesn't seem to take into account the request to mention that it only impacts non-transparent backgrounds - was that a deliberate omission? The new example 4 looks like perhaps it is supposed to render as the images in the annex - if this is the case wouldn't it be preferable to put the annex example directly into the forcedDisplay section and remove that annex? LC-2975: a search for "subtitle document" reveals 2 instances remaining. LC-2979: I don't understand the new statement: "A Document Instance should use either the offset-time or offset-time syntax for all time expressions used therein." Did you mean: "A Document Instance should use either the clock-time or offset-time syntax for all time expressions used therein." ? Also, I can't see how the new statement actually addresses the comment. LC-2981: I see what you're getting at here but I think this needs some more editing to make the point clear. Specifically it does not state normatively the rule that text laid out using the relevant metrics must not extend in either direction outside of the region. 7.3 is currently: "The flow of text within a region depends the dimensions and spacing (kerning) between individual glyphs. The following allows the region extent to be set such that text flows without clipping. A Document Instance shall be authored such that glyphs that match the combinations of computed font family and code point listed in A. Reference Fonts are laid out using metrics equal to the metrics of the specified reference font, unless the glyph is not defined by the reference font." I'd propose: "The flow of text within a region depends on the dimensions of individual glyphs and the spacing (kerning) between them. The following allows the region extent to be set such that text flows without clipping. A Document Instance shall be authored such that when text using the reference fonts is laid out it does not extend in either the inline or block progression direction beyond the Content Rectangle [XSL 1.1] of its containing region. This applies to text that uses glyphs that match the combinations of computed font family and code point listed in A. Reference Fonts laid out using metrics equal to the metrics of the specified reference font, unless the glyph is not defined by the reference font." where [XSL 1.1] is as in TTML1. LC-2967: Example 10 is very minimal! It would be more useful to include all the extensions defined for the text profile in this example. Similarly Example 11 would benefit from use of altText.
