Not to look a +1 gift horse in the mouth 8-), but actually the use of
the 200 and 500 response codes was an indication to me that SOAP 1.1
used HTTP as a transfer protocol too.  SOAP 1.0 and SOAP 0.9 were the
culprits that used 200 for everything, IIRC.

I do agree that SOAP 1.2's integration with HTTP is tighter though,
save for ImmediateDestination 8-)
