I was at first puzzled, but you are right.  

<element name="foo"><list><empty/></list></element> 
matches <foo>  </foo>, but <attribute name="foo"><list><empty/></list></element>
does not match foo="  ".

><list><empty/></list> could be transformed to <value

Since we allow <list>p</list> where p can be empty, I do not think that this is  
an improvement.

Cheers,
