Just out of interest's sake, in your experience, is there a *right*  
way to interpret the payload of the message?

With IDL/WSDL you know ahead of time how to decode the payload, if you  
defer it to a *dynamic* approach, IMHO you have to some kind of a  
priori knowledge of the structure of the data and have to be able to  
create instances of those data structures on the fly in your target  

I ask this question because I took the following approach ( http://hopper.squarespace.com/blog/2008/5/22/pet-store-part-1.html 
  ) to the problem you are talking about, but am just questioning  
whether my own approach has any merit at all.
