public interface SVGItem

This interface represents an item in an SVGXXXList. The item is required to hold a reference to its parent list so that an item can be moved from one list to another. A string representation of the item is also required in order to update the value of the attribute the list containing the item represents. If the value of the item is changed, it is required to notify the list it belongs to in order to synchronized the list and the attribute the list represents.
