The CSS2 draft gives the value for 'cue' [1] as

Value: <'cue-before'> || <'cue-after'>

This allows two URLs for the 'cue' value, but IINM the intention is for 
only one URL to be specified:

Value: <url> | none

If two URLs are intended, then the current value does not allow the UA to 
know which should be cued before and which should be cued after.  Perhaps 
the following would be most suitable:

Value: [<url> | none]{1,2}

where the first value indicates the 'cue-before' value, and the second 
indicates the 'cue-after' value.  If only one value is given, it becomes 
the 'cue-before' and 'cue-after' value.  (This is analogous to the box 
properties like margin [3] etc.)

For 'play-during' [2], the value is given as

Value: <url> | mix? repeat? | auto | none

but I believe the intention is

Value: <url> mix? repeat? | auto | none
