We have slightly amended the specification to point to SMIL2.0
throughout, and we find that it is clear. Additive refers to the way
that the base value may be changed; cumulative refers to repeating
animations. They are distinct, but related.

Correct.

BH> Please change the draft such that this is clearly defined.

We have 2 links to the SMIL 2.0 spec, 1 for additive, and 1 for
cummulative; and we have an attribute to control this - accumulate

The clear definition is to be found in the referenced SMIL2
specification:

http://www.w3.org/TR/SMIL/animation.html#animationNS-Accumulate

Please let us know within two weeks if this does not satisfy your
comment.
