Why do we need encoding-style?

[Gaurav]

Hi all,   What exactly is meant by "encoding-style" attribute in SOAP message. I read that "encoding-style"  value informs the server of the encoding style used to encode -- i.e., serialize -- the method. But dont we use XML to serialize the method in SOAP?? So why would we use an encoding-style attribute? Does anybody have any example which shows utility of this attribute in a practical scenario?   Thnaks and regards, Gaurav
