How are geometries stored in a KML file?
An ArcGIS API for JavaScript KML layer can be thought of as more of a group layer rather than a single layer. Geometries from a KML file are stored as feature layers: one each for points, lines and polygons. Feature layers for a particular geometry type are only created if there are features of that geometry type in the KML file.
