dirkschulze has just labeled an issue for https://github.com/w3c/svgwg as "Needs editing":

== Definition of `transform` attribute in SVG 2 is not backward compatible to SVG 1.1 ==
SVG 2 spec [says](https://www.w3.org/TR/SVG/coords.html#TransformProperty):
> User agents must support the transform property and presentation attribute as defined in [css-transforms-1].

While SVG 1.1 spec contains [the complete definition of such attribute](https://www.w3.org/TR/SVG11/coords.html#TransformAttribute).

There are two differences as far as I can see:

One is CSS transform functions doesn't support comma-separated parameters, while SVG 1.1 ones do. (I think this was discussed at some point somewhere, but failed to figure out with a brief search.)

The other is that `rotate()` function in SVG 1.1 supports specifying origin, but its CSS counterpart doesn't.

Maybe we should add those into css-transforms to make SVG 2 compatible to SVG 1.1?
