We're defining what "class" means for HTML(5), and what the behaviour of 
getElemetsByClassName() in the DOM should be. But if someone invents 
FooBarML that has classes with spaces in it, CSS will match them (for 
example, ".a\ b"), and I don't see why getElementsByClassName should not 
be capable of matching them given that it falls simply out of the current 

However, this is all highly theoretical.
