Problem Using changeType On execQuery Result

I am trying to read the result of an execQuery.  My xml document (give at the end of this email) gives test data (namely what accounts are used for each test).  I have written an xquery expression to figure out the account ids to use for each test.
 
 Here is the code I am trying to get to work:
 
             TestDataDocument testDataDocument = TestDataDocument.Factory.parse(new File("aws-test-data.xml"));
             String queryExpression = 
                 "declare namespace aws='http://test.aws.couball/data'; "+
                 "for $a in /aws:test-data/aws:tests/aws:test[@name='Test1']/aws:accountref/@name "+
                 "return /aws:test-data/aws:accounts/aws:account[@name=$a]";
 
             XmlObject[] xmlObjects = (XmlObject[]) testDataDocument.execQuery(queryExpression);
             log.debug("xmlObjects.length="+xmlObjects.length);
             for (XmlObject xmlObject : xmlObjects) {
                 log.debug(xmlObject.getClass().getName());
                 AccountType account = (AccountType) xmlObject.changeType(AccountType.type);
                 log.debug(account.getClass().getName());
                 log.debug("account.getId()="+account.getId()+", account.getName()="+account.getName());
             }
 
 I believe that I am getting the right data selected in the xquery expression since I can use a cursor from each xmlObject and traverse to see all the nodes I expect.  The problem is with utilizing changeType.  The account object in my sample always returns null for getId() and getName().  AccountType is a generated xmlbeans object from my schema.  Am I missing something here with .changeType?  Or am I on the wrong track.  Any advice would be appreciated.
 
 Here is the log output I receive when running this snippet:
