title: Validating SOAP message against WSDL with multiple XSD's
body: <p>I've been looking around the net for a good few hours now, trying to find a simple way to validate a full SOAP message against a WSDL. I am aware that there are ways to do this with the various Web Service frameworks out there, but I don't want to do this as the requirement is simply to validate a piece of XML. I could validate against the schema, although the problem I have is that there are a number of schemas imported into the WSDL and I don't know which one I should be validating against. I could write some utility to first process the WSDL and the response to determine which XSD to validate against, but I presumed this could be done as a one-liner using an established library! </p>
  
  <p>Does anyone know of a relatively straightforward way to validate an XML document given a WSDL and multiple XSD's?</p>
