This function constructs a geospatial element index specification.

$namespace The namespace URI.
$localname The local name for the node.
$coordinate-system The coordinate system. Must be one of wgs84, wgs84/double, etrs89, etrs89/double, raw, raw/double.

$invalid-values An option to handle values that do not meet the range index type. Must be one of: reject (default), ignore.
