OK, not so fast, mate.  Do you really think we'll let yer out so easily after 
yer talked us into this?

Seriously, after a quick survey of my code, the only place I import Node is in 
order to get at the constants.

I think we can deal with the problem you mentioned by re-naming 
xml/dom/Node.py, perhaps to xml/dom/FtNode.py and then adjust all the internal 
4DOM imports accordingly.

This should break little existing code and it would keep the nenefit of being 
able to share the constants and any other material we need for normalization 
across the DOM implementations.
