geogml functions (GML)
The GML module provides support for geospatial queries using GML markup.
To use the GML module as part of your own XQuery module, include the following line in your XQuery prolog:
import module namespace geogml = "http://marklogic.com/geospatial/gml"
at "/MarkLogic/geospatial/gml.xqy";
The library namespace prefix geogml is not predefined
in the server.
