additive

This attribute controls whether or not the animation is additive.

It is frequently useful to define animation as an offset or delta to an attribute's value, rather than as absolute values. This attribute said to the animation if their values are added to the original animated attribute's value.

Usage context

Specifies that the animation will add to the underlying value of the attribute and other lower priority animations.

This is the default, however the behavior is also affected by the animation value attributes by and to, as described in SMIL Animation: How from, to and by attributes affect additive behavior.
