According to CSS Transitions...
>Value: none | <single-transition-property> [ ‘,’ <single-transition-property> ]*
><single-transition-property> = all | <IDENT>
On Windows 7 Home Premium SP1 64bit, Firefox Nightly 21.0a1(buildID 20130217031005) corresponds to this.
But Chromium 27.0.1416.0 (183049) doesn't accept "all, <IDENT>" in transition-property property.
Moreover, It seems that transition-property property and transition shorthand property can't accept "all, all",
but transition shorthand property can accept "all, <IDENT>".
I can't find description like ‘"all, <IDENT>" is invalid’ in the spec.
I'm sorry if I'm wrong.
