Class names as CSS selectors are somewhat confusing to authors, but in  
my experience less so than namespace prefixes. I think there are a few  
reasons: (1) indirectly binding style is less surprising to people's  
expectations than indirectly binding meaning/identity, since the  
indirection links two separate things rather than modifying meaning;  
(2) it's harder to make the mistake where you think the class name for  
actually *is* the style, than to make the mistake where you think the  
prefix *is* the namespace, in fact I have not heard of anyone making  
this particular mistake; (3) the effects of incorrect style binding  
are likely to be more immediately visible in the context where they  
are authored; (4) the binding rules of CSS are simpler and so less  
likely to lead to unnoticed copy/paste errors in markup.
