Sorry, looking at the mails linked to in this thread, this issue appears to be referring to SMIL. I [argued about a decade ago](https://birtles.wordpress.com/animatetransform-issues/by-animation-and-scale-transformations/) that the underlying value for scale should be 1 in SMIL. The SVG 1.2 Tiny test suite, however, used zero so I made Firefox follow that. I don't know if it's worth trying to fix SMIL now, or at least not `<animateTransform>`. We could try to fix it for `<animate>` I guess. The ["neutral value for composition"](https://drafts.csswg.org/web-animations-1/#neutral-value-for-composition) is something internal to Web Animations. It's just a roundabout way of saying, "use the underlying value". It should probably be dropped and it doesn't need to be defined here. I would just say that for SVG animation, the underlying value used for a by-animation of transform is a zero matrix. -- GitHub Notification of comment by birtles Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/932#issuecomment-356183123 using your GitHub account
