Thanks for all the help and links guys, much appreciated. After all the suggestions and in-depth links, if I understand it correct, the way to go is using the normal class with optional var properties, for the default constructor, take all the mandatory fields first, then the optional fields.

Sounds mostly ok, but I am not sure about the "optional var properties" part. You can use mandatory var properties as well.
