<wait>

This can be used to wait for some time, see e.g. wait.asd:

<asdf version="0.4">
  <clip file="audio/xmas.wav" pos="-1.5 1" />
  <wait dur="5" />
  <clip file="audio/ukewave.ogg" pos="1.5 1" />
</asdf>

dur

The wait duration can be given either as a time duration or as a percentage of the parent duration. The same syntax as in the time attribute of transform nodes is supported.
