The name can be used to help find relative schema/dtds - though it shouldn't
be used in the compare. Will patch.

Sure!
I seem to remember IBM doing one that was based on W3C DOM.
Incidentally whenever 2 docs are different and you're trying to figure out
why, deriving from the org.dom4j.AbstractTestCase class in dom4j/src/test
could be useful. Its got a lot of JUnit style assertion helper methods. So
if you do....
public MyTest extends AbstractTestCase {
public void testFoo() throws Exception {
...
assertDocumentsEqual( doc1, doc2 );
}
then it will tell you exactly what is different between the docs. Just
getting a positive number isn't that helpful ;-)
