== GIS Import/Export ==

We need to be able to Import & Export these XML formats to/from the Database:
 * GeoRSS (URL fetch/publish)
 * GPX (File upload/download)
 * GML
 * KML (File upload/download & URL fetch/publish)
 * OSM (File upload/download)

This is probably best-done using an XSD parser:
 * [http://georss.org/gml GeoRSS]
  * http://georss.org/xml/1.1/georss.xsd
  * http://georss.org/xml/1.1/gmlgeorss.xsd

This is one option for Import:
