title: JAXB unmarshaling xml without qualified namespace prefixes
body: <p>I need to marshal object to xml with qualified namespace form (<code>&lt;prefix:tag-name&gt;</code>).
  And it works fine. 
  I have package-info.java file with <code>@XmlShema(elementFormDefault=XmlNsForm.QUALIFIED)</code> but xmls I received comes without namespace prefixes (<code>&lt;tag-name&gt;</code>).
  Is there any way to use namespace prefixes just for marshaling with Java 8?</p>
