So I agree it would be if all UAs followed the same model and I hope they  
do so for the majority of the cases, but we shouldn't prevent UAs from  
coming up with alternative (default) UIs if they so desire. I guess a RFC  
2119 SHOULD would cover that, but I'm not entirely sure.

The problem I have with "child elements must be treated like bitmap  
images" is that it seems to assume some default treatment for bitmap  
images that isn't really clear from the text.
