Ok, for the unknown media features, unknown media feature values, and  
malformed media queries this should now be as clear as we can make it. If  
I'm going to write the next version of Media Queries I will turn it all  
into a single coherent model, including parsing, serializing, the CSSOM,  
etc.

If parsing returns a single media query that is "not all" and "not all" is  
not in the list it will be appended. If parsing returns multiple media  
queries or if it returns something that is already in the list nothing  
will be appended.

Ok, done.
