`<asdf>`#

An ASDF file must contain a single top-level <asdf> element with a required version attribute. Currently, only version="0.4" is supported.

The <asdf> element can optionally contain <head> and <body> sub-elements.

If there is no <body> element, all sub-elements of <asdf> (except an optional <head> element) are treated as if they were contained in a <body> element, which in turn behaves like an implicit <seq>, see <head> and <body>. For example, the clips in implicit-seq.asd are played in sequence:

<asdf version="0.4">
  <clip file="audio/xmas.wav" pos="-2.5 0" />
  <clip file="audio/ukewave.ogg" pos="2.5 0" />
</asdf>
