1My goal is to build a high quality GPX (GPS Exchange Format) in OCaml, using 2the xmlm streaming code library to make the core library portable. Then build a 3Unix-based layer over that to implement the IO. 4 5The GPX homepage is at https://www.topografix.com/gpx.asp with the XSD scheme 6at https://www.topografix.com/GPX/1/1/gpx.xsd and the docs at 7https://www.topografix.com/GPX/1/1/ 8 9
