Update Mode
The writer supports writing features to either parent <Document> element, or a <NetworkLinkControl> element that itself contains <Update> elements. The writer also supports creating <AnimatedUpdate> elements that themselves contain <Update> elements. Any feature that has a kml_update_mode attribute is designated a “Update” feature, and will be routed to an <Update> element. If the kml_tour and kml_animated_update format attributes are specified, the update feature will be routed to the corresponding <Tour> and <AnimatedUpdate> objects, otherwise, the update feature will be routed to a <NetworkLinkControl>.
