Dear all, I have the following schema element types: Vehicle <--- MyVehicle ^ ^ | | Car <-- MyCar Vehicle is the base element type. Car extends from Vehicle. I want to add new elements to Vehicle, so I've created MyVehicle. Now I want to extend Car with MyCar, but I want MyCar also to have MyVehicle new child elements. Any idea about how to get this? I don't want to change or redefine Vehicle or Car as they are official elements, but I want to be able to extend them to add new child elements. The problem in Java or other languages is only solved for operations (using interfaces) but not for properties. I was thinking in using element groups instead of inheritance but then I can't use substitution groups. I want to use them so I could be able to use MyVehicle in all places in a XML document where Vehicle is allowed. Thank you very much. Kind Regards, Leo Antoli
