NamespaceBuilder does not create child nodes

	@Test
	void testNamespaceBuilder() {

		def n = new Namespace('http://foo/bar')
		
		def builder = new NamespaceBuilder(new NodeBuilder()).namespace(n.uri)
		Node node = builder.crap(id:"3") {
			bucket(name:"foo")
		}
		// ** this prints out only the "crap" element, not its child
		new XmlNodePrinter().print(node)

		// *** fails
		assert node[n.bucket][0].@name == 'foo'
