Justin Rudd has a post that's interesting. The most intriguing part is about how he's writing a framework that's similar to what Tim Ewald demoed at WS DevCon. I had asked Tim about releasing the source, and he sounded open to that, but he's probably moved on to other things by now. The start discusses using bare parameter style. I'm going to look into this. Part of the experiments I'm doing with controlling WSDL generation relate to the way we write services at work. The issue is that we'd like to strongly type the WSDL contract; rather than specify XML parameters using , we'd like to attach a schema for the document being passed. At the same time, we don't want to go down the road of mapping this to objects, because on the server side we deal with the parameters as XML. If a client wants to map the XML to objects, that's fine, if they want to do it as XML, then they have the schema available.
