title: Use Savon SOAP to investigate parameters
body: <p>In order to do some investigative and debugging work, I would like to find out about the required and optional methods for a SOAP with WSDL. </p>
  
  <p>In that WSDL, all required and optional parameters foor each SOAP action, as well as their type and form, are described. </p>
  
  <p>Is there a way to extract these inside <a href="https://github.com/rubiii/savon" rel="nofollow">Savon</a>?</p>
