The error message tells you that the XSD is invalid. You can't have a named type nested inside anything else other than a schema or redefine .
In the XSD, you are using two different elements: extraImages and extraImage But in your XML, you are using extraImages twice instead of using extraImages and extraImage once each.
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.
