 	Specifying a hue interpolation strategy is already part of the <<color-interpolation-method>> syntax
 	via the <<hue-interpolation-method>> token.
 
-	Both angles and their difference need to be constrained to [0, 360) prior to interpolation.
-	To do this, the minimum number of turns that fit in the lesser angle
-	is added or subtracted from both angles,
-	bringing the lesser angle into the range [0,360);
-	and if the difference between them is greater than or equal to 360&deg;
-	then the minimum number of turns to bring the difference into the range [0,360)
-	is further subtracted from the greater angle.
-
 	Unless otherwise specified, if no specific hue interpolation algorithm is selected by the host syntax, the default is ''shorter''.
