Does anyone know of any documented set (i.e. available on the 
internet somewhere) of WSDL changes that break existing consumers, 
and has been verified via testing?  I'm looking for a table that 
would contain a list of changes, and then the behavior of various 
SOAP stacks.  For example, I know that adding an operation to a web 
service has no impact on an existing WebLogic consumer of that Web 
Service.  I also know that adding attributes to a response message 
doesn't impact .NET clients that aren't interested in that attribute, 
as long as the structure of the rest of the message remains consistent.

I am looking for things that have actually been tested, versus 
hypothetical behavior.  One can presume that adding an operation 
should not require a rebuild of existing clients except in the case 
where those clients need the new operation.  That being said, the 
client side proxies are built using ant tasks, wizards, etc., and 
what goes on inside of that generated code is unknown.
