I am a bit surprised that the proposal I made for how to eliminate 
message is not interesting to more people. Basically what I proposed
allows one to use a single XSD element or type for the 80% case and
IF ONE WISHES to document more than one input or output element or type,
then they can indicate it. That's a nice way to cleanly support the
attachment stuff, for example (such as additional XML documents or
GIF images people may want to send along with their SOAP envelope).

It seems like a middle-ground that allows the people happy with just
modeling the world with schema to do so, but allows others to life
happily too.
