Example

  xquery version "1.0-ml";
  import module namespace geokml = "http://marklogic.com/geospatial/kml"
         at "/MarkLogic/geospatial/kml.xqy";
  declare namespace kml="http://www.opengis.net/kml/2.2;"

  geokml:polygon((
    <kml:Point>
      <kml:coordinates>-127.24,12.5</kml:coordinates>
    </kml:Point>,
    <kml:Point>
      <kml:coordinates>-127.8,15.25</kml:coordinates>
    </kml:Point>,
    <kml:Point>
      <kml:coordinates>-126.1,13.45</kml:coordinates>
    </kml:Point>,
    <kml:Point>
      <kml:coordinates>-127.24,12.5</kml:coordinates>
    </kml:Point>
  ))
