... and:

    <p>hello <i>sweet <b>world</b></i>.</p>



I don't like you chances of selling that to anyone. Also, we have both conveniently
omitted the spaces between words - if inserted, a slightly different example of:

   <p>hello <i>sweet</i> <b>world</b>.</p>

... might become:

   <p><plain>hello </plain><i><plain>sweet</plain></i>
   <plain> </plain><b><plain>world</plain></b><plain>.</plain></p>

Just as the period isn't supposed to be emphasised, one could argue that the spaces don't
belong to the elements either. If the element was a partnumber, it would probably be
incorrect to insert an additional space - that means that you have to deal with them
separately, not just bundle them into a convenient element. I don't see much future for
your proposed approach.
