David Baron has suggested he prefers a different type of error handling  
for unknown media types. E.g., that 'not foo' evaluates to true and  
instead of being ignored. This would avoid having to hardcode a specific  
set of known media types. E.g., if 'not projection' was to evaluate to  
true as well in user agents not supporting projection. (This would also be  
more in line with existing implementations of Opera and WebKit.)

If we do this I think it would be the first time an unrecognized IDENT  
ends up in the CSSOM. I'm not really convinced that's a good idea, but I  
don't feel strongly about it.

Unless more people are opposed I'll try to make this change before the  
telcon tomorrow so we can move forward with this specification again.
