And why is it I think you are right? :-)

Some of the XML files used by bioinformaticians can be horrendously large 
and at least some of the XML packages do appear to behave like they bring 
the whole file into a memory representation before allowing you to work on 
it. I think memory use and performance was a major factor in the current BJ 
implementations adopting an event-based model even though it's more 
difficult to use usually.
