The issue is how to present a certain normalized view of an XML document
(with entities). A SAX filter might expand entities into text,normalize text
and hence present this logical view of an XML document. This view can serve
as the input to either a DOM or another piece of software which provides a
DocumentHandler/ContentHandler interface.
