[css3] About opacity

Hi there.
I'm sending this e-mail because I looked around and couldn't find anything
about it. So, I'm sending this little idea.

It is related to the implementation of opacity. I have thought on this:

<style type='text/css'>
#parentEl
{
  padding:10px;
  opacity: 0.5;
  background-color:blue;
}
#son
{
  width:40px;
  height:40px;
  opacity:1;
}
</style>
<div id='parentEl'>
    <div id='son'></div>
</div>

Well, the point is that ... I believe it would be better if the son could
restore its opacity to 1, if it s set to it, instead of always applying its
parent opacity plus its own opacity.  In this case, we would be able to
easily implement a transparent background with opaque content. When working
with RIAs, worrying about the look of the application, it may be very handy
:)

Well, that's all. Thanks for your time.
Best Regards.
