I tested this by taking Saxon out of the equation: if the program is reduced
to:

DocumentBuilderFactory df = DocumentBuilderFactory.newInstance();

DocumentBuilderFactory is evil. Your mistake (and probably the original mistake) is forgetting to make it namespace aware like so:

df.setNamespaceAware(true);

sad but true: DocumentBuilderFactory is broken unless you explicitly turn on namespace handling.

org.w3c.dom.Document doc = df.newDocumentBuilder().parse(new
File("mmlkit.xml"));
Element outer = doc.getDocumentElement();
NodeList outerKids = outer.getChildNodes();
DOMConverter.convert ((org.w3c.dom.Element) outerKids.item (1));

then it fails with the same error.
