so how difficult it is to generalize it to support multiple view and 
switching between them through controller like:

XmlObject.castOrWrap(Object o, Class targetInterface);

for example

PurchaseOrderElement po = (PurchaseOrderElement) XmlObject.castOrWrap(Node node, PurchaseOrderElement.class);

alek

ps. in JDK 1.5 i think it can be somewhat shortahnded to avoid casting:
PurchaseOrderElement po = XmlObject.castOrWrap<PurchaseOrderElement>(Node node);
