Both are horrible. Mozilla's because the string is a transparent blob that's parsed separately to the rest of the CSS syntax and Microsoft's because it's dependent on ordering. I don't see why a boolean value wasn't an option; the values is either defined or it's not. Otherwise "kern(1)" would have been more consistant with other properties.
