`source`	`*`		A source with the KML data. See `load()` function for additional details.
`expanded`	`Boolean`	`false`	Defines whether `toXML()` method should return full KML <Container> node, rather than a <NetworkLink> node.
`keepXML`	`Boolean`	`false`	Defines whether to keep XML data in memory after it has been loaded. To access stored XML data, use `xml` property.
