Hierarchy makes sense, recursion doesn't.  Recursion often causes more 
memory to be used during a parse because information relating to an 
element's extended family needs to be kept.  Of course, a hierarchy can be 
recursive, which is good for a DOM-based approach (finding the value of an 
element in a logical order), but it is less useful to an event based parser.
