title: JAXB unmarshal exclude specific element
body: <p>I know for <strong>@XmlTransient</strong> annotation, but sometimes I need this element and in other use cases I really have to prevent it from unmarshaling, because it contains base64 text. So I need to exclude it because performance problems.</p>
  
  <p>Is there any way to <em>dynamicly exclude</em> one element from unmarshaling with JAXB?</p>
