This is an interesting question from the public list.

The syntax I had been assuming for all multi-part CSS properties was:
  play-during="'url' mix"
  border="12pt dashed red"

We have also gotton several questions regarding whether one could state:
  space-before="12pt 24pt 36pt force discard"
and what is meant by (if allowed):
and what is meant by (if allowed):
  space-before="12pt" space-before.minimum="6pt"

I think the syntax for these needs a section in the spec.
