	<annotation>
		<documentation>Envelope defines an extent using a pair of positions defining opposite corners in arbitrary dimensions. The first direct 
		position is the "lower corner" (a coordinate position consisting of all the minimal ordinates for each dimension for all points within the envelope), 
		the second one the "upper corner" (a coordinate position consisting of all the maximal ordinates for each dimension for all points within the 
		envelope).</documentation>
