RTZ schema version 1.2. For more information on RTZ and this schema, visit http://www.cirm.org/RTZ. RTZ uses the following conventions: all coordinates are relative to the WGS84 datum. All measurements are in nautical miles unless otherwise specified. Route is the root element in the XML RTZ file. RTZ files contain a number of waypoints, followed with auxiliary schedules. You can add your own elements to the extension section of the RTZ document. Generic route information. A list of waypoints. Optional list of schedules. You can add extend RTZ by adding your own elements from another schema here. Format version (currently "1.2"). You can add extend RTZ by adding your own elements from another schema here.
