You should change MyMap as below. XmlArray and XmlArrayItem are the magic attributes.
One way to find a solution would be to populate the object in code and then serialize it to xml, and see what the schema looks like. Also you could use xsd. Exe to autogenerate your classes.
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.
