Usually, you'd create a parser module that offers a SAX parser only;
it can then be used to build DOM trees. If the parser has its own DOM
implementation, you could also expose that - but that's quite some
work to wrap all the classes.

Not sure what "the whole subsystem" is. If you have a SAX parser, and
you want to create a DOM tree, you can use pulldom to create a minidom
tree, and xml.dom.ext.reader.Sax2 to create a 4DOM tree.
