YMapsML is a language for describing geographical objects.
In YMapsML, each geographical object is associated with a geometric shape and a geo object that is used for displaying this shape on the map. The shape definitions and their anchors to geographical coordinates are set in corresponding YMapsML elements. The gml:LinearRing element is designated for the "linear ring" shape. This element contains the coordinates of line endpoints. The coordinates of the first and last endpoints must match.
The geoXml.load function is used for loading YMapsML data. After data loads, the function converts it to GeoObjectCollection and passes it to the handler function as a parameter. A GeoObjectCollection can be displayed on the map.
