title: Validate XML instance document against WSDL
body: <p>I can easily validate a <strong>XML document</strong> against a <strong>XML Schema</strong>, eg. with <strong>XMLSpy</strong> or programmatically. 
  Is it possible to do this with a <strong>WSDL</strong> file? It does not seem possible with <strong>XMLSpy</strong> or any other XML tool I know. For me the only possibility right now is to do it programmatically, eg. by generating Java code from the <strong>WSDL</strong> and starting a request, which is then marshalled correctly.
  If there is no tool / easy programmatic approach, is there a tool which can extract <strong>XML Schema</strong> from the <strong>WSDL</strong>?</p>
  
  <p>Best</p>
