I'll have another look at the XML and the C# files it produces this week and try to pick out other things. Basically i want to make sure that all required fields are definitely required. I have written a tool (based off xsd.exe) to do custom serialization on all optional fields so that if its the default value the xml doesn't get unnecessarily written to the file. For now it should be fine as long as the <choice> tags are fixed
