title: How to add a custom header to cxf soap requests?
body: <p>I'd like to create the following xml by using <code>cxf</code> and <code>spring</code> soap webservices:</p>
  
  <pre><code>&lt;soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:key="http://schema.to/WebService"&gt;
     &lt;soapenv:Header&gt;
        &lt;key:Signing&gt;asdasdasd&lt;/key:Signing&gt;
     &lt;/soapenv:Header&gt;
  </code></pre>
  
  <p>How can this be done? How can I set the namespace and the custom header tag element?</p>
