Interesting.

I like it. I have a project coming up that is going to require ripping 
through the same 1mb-5mb xml documents a lot. All of the required 
queries will be able to start from a unique position 
(nice_indexing_attribute) and will not need to traverse more than a 
dozen elements on average.

If I could cache the starting positions in a HashMap and force the 
VTD-XML xpath query to start at a specific position that would save the 
xpath query engine from having to walk through a lot of unnecessary data.

Just thinking out loud. I'm not sure if I understood if this is coming 
in 2.0 or not.

Cheers.
