…ent elements (#891).

Closes #891.

This change seems right to me, though I am not convinced that we can claim it is editorial. I'm approving it now but it would be appropriate to give this pull request the full review period and not merge early as an editorial pull request.

Taking a conservative position, I am relabeling this as substantive.

The full IRC log of that discussion

<nigel> Topic: Ensure audio and image (in presentation contexts) are treated as cont… ttml2#898
<nigel> github: https://github.com//pull/898
<nigel> Glenn: I think I just wanted to note that I've moved this to substantive. We discussed earlier.
<nigel> .. Pierre, you might want to take a look at this. It adds audio and image to content element.
<nigel> .. During the last meeting you had some questions and were reluctant to make this change.
<nigel> Pierre: Alright, em...
<nigel> Glenn: I went through all instances of the phrase content element in TTML2 and found
<nigel> .. no cases where it was not appropriate.
<nigel> Pierre: I sense that we've already had this discussion somehow and you argued for the
<nigel> .. opposite in the past, but you've done the research now?
<nigel> Glenn: Yes. It took me about a day!
<nigel> Pierre: I need time to think about it. I'll study it.
<nigel> .. You're saying it's not embedded content, just content?
<nigel> Glenn: It's still covered under embedded but also in content element. We already had
<nigel> .. "presentation related" which included image but not audio. This attempts to make it
<nigel> .. consistent.
<nigel> Pierre: I'll add this to my review list, thanks for pointing me to it explicitly.
