This confirms the point that the classification of elements into  
block-level and inline-level is just a convention not backed by a semantic  
requirement. Well, it establishes a rule about the valid and invalid  
element nesting, which does help error recovery. But as we are discussing  
the very error recovery at this time, maybe we should review this rule if  
it helps build a saner DOM for some pathological but widely used markup?
