I would just like to quote this post by Ian Hickson, which Iā??d happily 
agree with:

"We mustn't fall into the trap of considering everything to be a 
hierarchy, just because that is what XML most easily marks up. Book 
authors have managed quite well for centuries without considering their 
documents to be formed of trees! (Notwithstanding what paper is made of, 
I mean.)"
