*
* Validating your GPX document
* Validation is done using the Xerces XML parser. Download the latest Xerces distribution from the Apache website.
* Windows users should download the "Latest Xerces-C++ Binary Package for Windows". Unzip the files, and locate the
* SAXCount.exe program in the bin folder. This is a command-line utility that will validate your GPX file.
*
* Assuming your GPX file is named my_gpx_file.gpx, and is located in the same folder as SaxCount.exe, use the following
* command line to validate your file:
*
* SaxCount.exe -v=always -n -s -f test.gpx
*
* If your file validates successfully, SAXCount will display a count of the elements in your file, like the following:
*
* test.gpx: 1012 ms (4025 elems, 1916 attrs, 8048 spaces, 36109 chars)
*
* Any other output from SAXCount.exe indicates that your GPX file is incorrect. It is your responsibility to ensure that any GPX files you create validate successfully against the GPX schema.
