Forms handling is among the most important functions in a browser, the HTML 2.0 forms are seriously outdated and news.com.com considers the forms alternatives. As I see it there isn’t a conflict Web Forms 2.0 vs XForms. Web Forms is designed partially XForms compatible. There are substantial differences that run deeper than on the syntactic level (such as the names of the elements) and there is no tool today that can automatially turn arbitrary XForms forms into Web Forms. Some, probably most, forms will be very similar in the two languages both in structure and functionality and could be converted easily.
