It's not documented for stand-alone use.ElementInclude also isn't documented and doesn't appear to be usedanywhere.The facade can be added to xml/etree/ElementTree.py since that's theonly documented module. It can attempt to do:from _elementtree import *(which is what cElementTree.py) does, and on failure, just go on doingwhat it does now.Eli
