Nodetree has Document and root Element

I think an example will explain the emerging API far better than I can.

You can replicate this with the code from http://hg.concordance-xmpp.org/nodetree, though its still very early the code is completely documented in its current state.

>>> bar = nodetree.Element('bar')
