In addition to wanting to express my agreement with Don (and say thanks for
"A Brief History of SOAP"!), I'd like to point out that I believe that the
thread in [2] is related -- one (my) interpretation of the thread is: 

"how much encoding should we 'bake in' to the XMLP specification, vs. how 
much should we rely on the ability of XML Schema (or other content 
description language) to solve many of the problems a specific encoding 
might address (including binding to programming language datatypes)".

I don't think there is yet widespread understanding of exactly how
schemas can help relieve interoperability problems.  (Anyone?)
