I think that this is really up to the application, and where you're just using
SOAP to throw pieces of XML around, you're probably not going to want to access
your piece of XML while it's inside the envelope. I've never done anything with
SOAP, though. :-)

Well, I could contradict myself immediately and say that one advantage is that
you can access your XML inside the envelope. ;-)

I wonder if SOAP provides messaging semantics over and above HTTP or SMTP. I
should try and find out more on messaging.
