title: Should the SOAP header be specified in the XSD?
body: <p>I am writing a web service, thus also writing an XSD to pass to the appropriate collegues to tell them what the web service expects. The service has a SOAP header which contains some security information for authentication. Should this be specified in the XSD? If so, is it simply specified like other body elements?</p>
  
  <p>Thanks in advance.</p>
