The problem with this approach is that it's unwieldy, not impossible 
but not pretty. In this pattern, the data structures must be 
initialized in one class before calling parse, filled in in the 
ContentHandler during the parse, and then torn down or flushed after 
the parse in the first class. Being able to rely on 
startDocument()/endDocument() in the ContentHandler allows all the 
initialization  and tear-down code to easily go in the same class as 
the code that fills the data structure. It's all neatly unified. This 
doesn't necessarily do anything that the other pattern can't do. It's 
just cleaner and easier to follow by keeping all the related code in 
one place.
