Hmm. The problem I face was a method to assign a unique ID to each 
element on the page.

Lets say I construct an iterwalk object. But, during this phase, I would 
like to not only build the tree, but also add some of my own information 
to each node (such as a unique ID to each element). I'm not sure how to 
do this, without extending the etree.so file inside which iterwalk is 
implemented..

Cheers,
