Specifies that each repeat iteration after the first builds upon the last value of the previous iteration. |

Specifies that repeat iterations are not cumulative. This is the default. |
This attribute is ignored if the target attribute value does not support addition, or if the animation element does not repeat.
Cumulative animation is not defined for “to animation”.
This attribute will be ignored if the animation function is specified with only the to attribute.
