This is an abstract base class and cannot be used directly in a KML file.
It provides the id attribute, which allows unique identification of a KML element,
and the targetId attribute, which is used to reference objects that have already been
loaded into Google Earth. The id attribute must be assigned if the <Update> mechanism is to be used.
The following elements can be used wherever this element is referenced:
Document, Folder, Placemark, NetworkLink, PhotoOverlay, ScreenOverlay, GroundOverlay,
Tour,Camera, LookAt, Data, SchemaData, MultiGeometry, Point, LineString, LinearRing,
Polygon, Model, Style, StyleMap, TimeStamp, TimeSpan, Region, LatLonAltBox, Lod,Icon,
Link, Location, Orientation, Scale, ResourceMap, Alias, ViewVolume,ImagePyramid, Pair,
LineStyle, PolyStyle, IconStyle, LabelStyle, BalloonStyle,ListStyle, ItemIcon
