Yes.

That one has always been that way.  The idea was, "if you're doing  
this, you probably mean 'clear', so just call that."  I guess if you  
were holding all the attributes to set in a list, and the list was  
empty, then allowing an empty list would make it work cleanly, but it  
really doesn't buy you much.
