Summary: Diff failswith xsi:type and different prefix

Initial Comment:
This code:

import org.custommonkey.xmlunit.Diff;
String result = "<ns1:Square xsi:type=\"ns1:Shape\" xmlns:ns1=\"http://example.com/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"/>";
String correct = "<ns2:Square xsi:type=\"ns2:Shape\" xmlns:ns2=\"http://example.com/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"/>";
Diff diff = new Diff(result, correct);
System.out.println("diff:" + diff);
System.out.println("diff.similar(): " + diff.similar());


results in:
diff: org.custommonkey.xmlunit.Diff
[not identical] Expected namespace prefix 'ns1' but was 'ns2' - comparing <ns1:Square...> at /Square[1] to <ns2:Square...> at /Square[1]

[different] Expected attribute value 'ns1:Shape' but was 'ns2:Shape' - comparing <ns1:Square xsi:type="ns1:Shape"...> at /Square[1]/@type to <ns2:Square xsi:type="ns2:Shape"...> at /Square[1]/@type

diff.similar(): false

Message:
Actually, XMLUnit doesn't really support much of the XML-Schema Instance
stuff at all.

I've started to fix it in the 1.x branch and simply ignoring the namespace
prefix is trivial for this case, making sure the prefixes map to the same
NS uris seems more difficult, at least as long as I'm in Java 1.4 land.

Once this is fixed I'll roll a new release.
