Glenn, et al,

The DXFP specification includes support for styling, both in-line and
out-of-line styling.
However it does not support a class based styling model.

In subtitling, styles are most often associated with changes in the text
'role' (e.g. dialogue differs in presentation from music) or 'speaker' (Joe
- red, Frank - blue).

Could a mechanism be added to support this?

E.g. This might be represented in DXFP by utilising a class based style
mechanism that was sensitive to ttm:role and ttm:agent. Thus:

<style id="s1" style tts:color="white" tts:fontFamily="monospace-serif"/>
<style id="intro" style="s1" tts:fontSize="4%"/>
<style id="documentary" style="s1" tts:fontSize="10%"
<style id="music" ttm:role="music" tts:fontStyle="oblique"/>
<style id="joe" ttm:agent="joe" tts:color="red"/>

<div style="intro">
<!-- all text 4% high -->
<!-- all text monospace-serif -->
<p ttm:role="music">Quiet Violin music</p>
<div style="documentary">
<!-- all text 5% high -->
<!-- all text sans-serif -->
<p>White Large sans-serif</p>
<p ttm:role="music">White Oblique Large sans-serif</p>
<p ttm:agent="joe">Red Large sans-serif</p>

the ttm:role and ttm:agent attributes could be considered as implicitly
adding inline style attribute(s) to their container....
