This isn't really the problem that Lachlan was raising. He's just  
pointing out that semantic markup through widely shared convention  
works in practice without having to explicitly state that a document  
is following said convention.

I do see your point that more complex structures are more easy to  
recognize unambiguously.

(However, Microformats are not very strong on clearly defining  
conformance requirements for content using a given microformat and  
stating parsing requirements for content consumers, particularly in  
the face of nonconforming content. And the most widely used  
microformat is rel="nofollow", which has trivial structure.)
