How do you pass more complex xml to a WSDL mode proxy client request? I read from the WSDL Mode Manual [1] that in order to pass arguments to a proxy client call you either use the classmap or associative arrays. But it can't seem to wrap my head around setting xml attributes with either method.

I'm working with a web service that expects a pretty complicated payload. I've attached a mock SOAP envelope with sensitive and really nonessential information pruned out for an example of what I'd like to be able to do with WSF/PHP.

Thanks in advance!
