title: Is there any way to Capitalize all elements via xStream?
body: <p>I am using xStream to format my XML.  </p>
  
  <pre><code>&lt;Messages&gt;
    &lt;message&gt;
      &lt;header&gt;
        &lt;origin&gt;
          &lt;Device&gt;
            &lt;deviceId&gt;deviceId&lt;/deviceId&gt;
          &lt;/Device&gt;
  </code></pre>
  
  <p>of course I can do this:</p>
  
  <pre><code>xstream.alias("Messages", Messages.class);
  xstream.alias("Message", Message.class);
  xstream.addImplicitCollection(Messages.class, "message", "Message", Message.class);
  xstream.aliasField("Header", Message.class, "header");
  xstream.aliasField("Origin", Header.class, "origin");
  </code></pre>
  
  <p>Is there some kind of global setting to upper case all elements?</p>
