I don't see how the analogy holds. Why is using a fairly clean namespace 
for predefined class names instead of a well-used one the same sort of 
thing as having HTML parsers stop at the first error?

(I guess I'm making an underlying assumption here that there aren't 
loads of existing pages on the web using HTML 5 predefined class names 
while expecting HTML 5 rendering and semantics for them. But, unless I'm 
missing something, that seems like a reasonable assumption.)
