  <pre><code>&lt;SOAP-ENV:Header&gt;
      &lt;SOAP-ENV:Header xmlns:wsa="http://admin.example.com"&gt;
        &lt;Username&gt;testuser&lt;/Username&gt;
        &lt;Password&gt;test123456&lt;/Password&gt;
        &lt;Signature&gt;5595610031002&lt;/Signature&gt;
      &lt;/SOAP-ENV:Header&gt;
    &lt;/SOAP-ENV:Header&gt;
