Parallel Media -- the par tag

We use the <par> to play media at the same time:

<par>
   <img src="cardiff.gif" alt="The cardiff icon"
        region="cardiff_icon" dur="6s" />
   <audio src="music.au" alt="Some Music"
         dur="6s" />
</par>

This will display an image and play some music along with it.
