Having the XSD generated from the existing classes sounds to me like the safest way to go.
You can use xjc and still have only one class with XML annotations that will server as a data object. But that is in case you are not re-generating the classes on each built.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
