Now that the AVM is gone, we have a new project (well, not yet to production) and they are using web forms. I have set up a 4.2.b with Web Quik Start. What is the closest thing to web forms in WQS?
The closest thing is the Share form service. You'll persist your content fields as properties on the node using custom types and/or aspects rather than as XML.
If your goal is to continue to capture XML then I'd suggest an integration with something like Orbeon or using a thick client XML editor.
