  Good question.  I don't know why character references need explicit
nodes in the DOM; I'm not terribly interested in knowing that
something was encoded as "&#43;" or "+".  I would like to be able to
have this:

<!DOCTYPE thing>

provide a reference to &foo; as a child of the <thing> node.  Here's
what I get now:

>>> buffer = '<!DOCTYPE thing>\n<thing>&foo;</thing>'
>>> import xml.dom.utils
>>> reader = xml.dom.utils.FileReader()
>>> import cStringIO
>>> sio = cStringIO.StringIO(buffer)
>>> dom = reader.readStream(sio)
>>> dom.documentElement
<Element 'thing'>
>>> len(dom.documentElement.childNodes)

And here's a bug ;-) :

>>> dom.documentElement.childNodes
