When you define a ‘signature’ in AWS it seems not to allow you to change  
the types in the return depending on the circumstances. On the other  
hand the xmlrpc spec seems specifically to disallow the return of both a  
result and a fault code/string - it must be one or the other.

Is there a way around this or does everying using AWS for xmlrpc break  
the standard? Have I missed something obvious?

Hey Steve,

I am also running with same issue.

I need to customize the xml output returned by API.

Have you got any solution to this issue?

Thanks,  
Piyush.
