Erez,
I’m with you. In order to provide this capability we’d really need XDoclet to be able to provide it first. There’s also the problem that some people may generate and then edit the generated files. It could prove tricky to pull this one off well. 🙂
In the meantime, I’d suggest using the package mapping facility in XDoclet to ensure that all your generated files go into packages that contain only generated files. This will at least make manual elimination easier.
