   [XNA] Default XML Values
  Hey,Is it possible to set up an XML to have default values for certain elements?What I am trying to do is add a new member to my base game object class.  These objects are initialized by reading in XML data into a Definition class.    public class GameObjectDefinition    {   // The position of the object in the world.  In the case of a 2D   // element, the Z component will be ignored.   //   public Vector3 mPosition = Vector3.Zero;   // The pitch, yaw and roll of the object in the world.  In the case   // of a 2D element, the rotation will be based around the Z axis (roll).   //   public Vector3 mRotation = Vector3.Zero;   // The scale of the object, with 1.0 being equal to it's original value.   //   public float mScale = 1f;// !! THIS IS WHAT I AM ADDING !!   // The priority is used to decide what order the object is rendered.  Most of   // the time this can just use the default value.   //   public int mRenderPriority = 100;    }But I don't want to have to go through every existing XML file in my project and add the mRenderPriority element, just to assign it a default value.  I'd like to just add it to the Game Object who want a value other than what I deem the default value.Is this possible?I get this error if I don't add it to any XML files:Error1XML element "mRenderPriority" not found.I load the XML data using the XNA Content Manager:  GameObjectDefinition definition = GameObjectManager.pInstance.pContentManager.Load<GameObjectDefinition>(fileName);Thanks!
