RE: [ttml2] embedded content, background image styling, other edits

That note may also need to be referred to from the font-face section too?
It would seem that (except for ASCII / LATIN 1) as mentioned, the use of the Unicode ‘range’ element becomes almost mandatory when a resource is referenced internally?

Best,
John

Thanks! I'll follow up Nigel's proposal. As indicated, I don't view it as a strong requirement (for STL files)... Not sure about this concept for other large resources (like fonts)...

btw, for fonts, you should be using subsetted fonts, i.e., containing only glyphs for characters used in a document; with an ASCII or LATIN-1 only font, this won't make much difference, but for modern Unicode fonts covering multiple scripts or for CJK fonts, this makes a huge difference;

i will add a note in the section defining the font element reminding readers of this fact
