Do you happen to have an example that I could pump through "wsdl.exe"?

I'm hearing quite a bit about what WSDL does and doesn't do but am
confused about what SOAP is doing here.

Is it generally the case that the types are declared in XML Schema and
that a tool like "wsdl.exe" is used to generate bindings? If so, then
presumably "section 5" is not being used. And of course the HTTP/RPC
bindings are not used.

Is the SOAP Header used? If so, with what kinds of values? May faults be
and results be returned? May I mix in Internet protocols such as SMTP or
HTTP between BEA and VS.NET?

What would I lose if I sent pure XML and used wsdl.exe to generate
bindings from an XML Schema?
