title: Is SAAJ compatible with MTOM + XOP?
body: <p>I´m trying to use MTOM + XOP to return a byte[] in a Spring Web Service but when marshalling result it throws a SAXParseException with message:</p>
  
  <p>cvc-type.3.1.2: Element 'dataHandler' is a simple type, so it must have no element information item [children].</p>
  
  <p>It seems that after writing XOP tag, validator meet with it instead of the byte[] content that it expects and throws a SAXParseException with FATAL level that stops the process.</p>
  
  <p>I´m using:</p>
  
  <ul>
  <li>JDK 1.7</li>
  <li>SAAJ 1.3</li>
  <li>SOAP 1.1</li>
  <li>Spring 4.1.4.RELEASE</li>
  <li>Spring WS 2.2.0.RELEASE</li>
  </ul>
  
  <p>Thanks in advance</p>
