I think you're both right ;-)
How about a compromise:
* we add a warning to the JavaDoc that if you change the document in any way
then the XPath may no longer work.
* I add a patch such that the index notation [2] is used if there are
multiple siblings with the same QName.
such that
/root/nodeA/nodeB[2]/@attribute would occur if nodeA had 2 nodeB nodes but
root had only one nodeA node.
Sound like a good plan?

It's sure that if you modify the tree all xpath generation methods will
produce wrong path even they use position or not.

I agree I forget this important feature of XML...
