See RASTER_INFO for response.
If COORDSYS is not included as a child element, it is assumed that the coordinates used for GET_RASTER_INFO x and y are in the same coordinate system as the raster image. If COORDSYS is used in the request, the attributes are in the coordinate system defined by COORDSYS.
If an x,y coordinate is out of range, an ERROR message is returned instead of RASTER_INFO.
