XForms
Some more about XForms. Thanks to a presentation of Jörn Turner (Chiba) the capabilities of XForms are much more clear to me now. My suggestion of using the switch syntax for multi screen forms was right. But XForms is able to solve much more as I expected such as external validation functions through customized xpath functions or the use of XML-shemas to use customized data types. I have to admit that the integrety of W3C standards brings much more benefits as I thought it could do. Next step: a midi-complex prototype.
