title: JAXBElement<Boolean> vs boolean
body: <p>What exactly is <code>JAXBElement Boolean</code> and how can I set this to the boolean equivalent of "<code>true</code>"?</p>
  
  <p>Method:</p>
  
  <pre><code>  public void setIncludeAllSubaccounts(JAXBElement&lt;Boolean&gt; paramJAXBElement)
    {
      this.includeAllSubaccounts = paramJAXBElement;
    }
  </code></pre>
  
  <p>This does <strong>not</strong> compile: </p>
  
  <pre><code>returnMessageFilter.setIncludeAllSubaccounts(true); 
  </code></pre>
