The problem is that document order of nodes isn't required to be 
preserved in xpath, amazingly.  You can run into the same problems in 
XSLT.

As for the patch :

1) We depend upon dom4j for our xpath support, so I would ensure that 
you have the latest version of that before we try to fix it in DVSL.

2) it only solves the problem for applyTemplates(), not 
applyTemplates(String xpath), which I think we should do.  Thus, I 
think we need a more general solution.

If you could try the latest dom4j and report back, that would be great. 
  We can proceed from there.
