To implement this, I see 2 solutions:
	**double the duration d of the animation (<code>dur</code> attribute) et apply a scale and a symetry around t=0.5 to the animation function. For example the simple linear interpolation defined by <code>keyTimes="0; 1"</code> and <code>keyPoints="0;1"</code> becomes <code>keyTimes="0; 0.5; 1"</code> and <code>keyPoints="0;1;0"</code>. This doesn't work for <code>paced</code> animation though (which make use of an implicit, user-agent dependent animation function).		**double the duration d of the animation (<code>dur</code> attribute) and apply a scale and a symetry around t=0.5 to the animation function.

	* '''discrete''': this is a degenerate form of interpolation, because the resulting animation function is not continuous.
