/*!
 * \brief Print the WPS 1.0.0 process description XML document to stdout
 *
 * A module started with the parameter "--wps-process-description"
 * will write a process description XML document to stdout and exit.
 *
 * Currently only raster and vector modules are supported, but the
 * generation works with any module (more or less meaningful).
 * Most of the input options are caught:
 * * single and multiple raster and vector maps
 * * single and multiple string, float and integer data with default
 * values and value options (range is missing)
 * Flags are supported as boolean values.
 *
 * The mime types for vector maps are GML, KML, dgn, shape and zipped shape. 
 *
 * The mime types for raster maps are tiff, geotiff, hfa, netcdf, gif, jpeg and png.
 *
 * Mime types for space time datasets are tar archives with gz, bzip or without compression
 *
 * The mime types are reflecting the capabilities of grass and gdal and may be extended.
 *
 * BoundignBox support is currently not available for inputs and outputs.
 * Literal data output (string, float or integer)  is currently not supported.
 *
 * In case no output parameter was set (new raster of vector map) the stdout output
 * is noticed as output parameter of mime type text/plain.
 *
 * Multiple vector or raster map outputs marked as one option are not supported (wps 1.0.0 specification
 * does not allow multiple outputs with only one identifier).
 * Multiple outputs must be wrapped via a python script or created as group.
 *
 * In future the following mimetypes may be supported
 * mime type: application/grass-vector-ascii  -> a text file generated with v.out.asci
 * Example.: urn:file:///path/name
 * mime type: application/grass-vector-binary -> the binary vectors must be addressed with a non standard urn:
 * Example: urn:grass:vector:location/mapset/name
 * */
