Description
Not sure if I'm just going blind, but reading https://drafts.csswg.org/css-transforms-2/#individual-transforms I can't see a definition of the additive or accumulative composite behavior for the individual properties ('scale', 'translate', 'rotate')? There's a section for transform-list, but that isn't relevant (afaict) for the individual properties.
I've attempted to reverse-engineer it from the WPT test but it isn't always clear. E.g. it seems reasonably clear that 'scale' has an additive behavior of multiply, but it's accumulative behavior isn't clear from the examples.

Research direction
Start with the Individual Transforms section in the css-transforms-2 draft and compare it with the transform-list section. Then inspect web-animations/animation-model/animation-types/addition-per-property.html and its WPT results, focusing on the additive and accumulative behavior of scale, translate, and rotate. Done means the specification clearly defines both behaviors for each individual transform property.
