Your very correct, I had left out normal thinking
that it wasn really a level of emphesis, but your
correct, it is. I had also completely forgotten
about <em><strong/></em>. While I aggree that this
does acheve the effect, it still does not semanticly
describe the emphesis.

I don't think nesting emphesis tags properly
describes what you are doing (ie: increasing or
decreasing emphesis) semanticly. Just because the
elements are nested doesn't mean they should act on
each other. Also, this doesn't allow for de-emphsis.

It shouldn't be too hard to add a level attribute.
The tabindex already allows for "0" and "-1", I'm
admittly unfamilular with schema though so its
probably more dificult than I think.

Thats along the lines of what I was thinking. It would
be a matter of i18n to best represent this in other
languages.
   level -1 - progressivly decreasing text size from
              here down.
   level  0 - normal
   level  1 - italic
   level  2 - bold italic
   level  3 - bold italic and increasing text size  
              progressively form here
I suppose it would be best to try to match typical
voice inflections as closely as possible for aural
browsers.
