What about dynamically generating a form action from XML/XSP?  Currently in
XMLForm you must create your own action to change "controller" behavior (i.e.
how navigation works and other stuff).  What if you have hundreds (thousands) of
forms with different controllers?  What if you build 20 different forms every
day?  Wouldn't it be easier to describe these controllers in xml/xsp than in
java?  This could even be part of some larger abstract form description which
would also describe data model in xml/xsp.  From larger abstraction would come
bean.java and wizard.java?  Model, view, and controller would all be described
in xml. Think markup developers rather than programmers/engineers.

Am I being crazy here?
