Description
Currently the spec of transform-origin contains the statement:
For SVG elements without associated CSS layout box the initial used value is 0 0 as if the user agent style sheet contained:
It would, on the face of it, be much more sensible to just define this as a UA style rule, rather than making UAs pretend.
(Given the wording "as if", does this mean WebKit's current implementation which uses a UA style rule is non-conforming?)

Research direction
Start in the CSS Transforms Level 1 specification at the transform-origin definition mentioned in the issue. Review how the initial used value for SVG elements without an associated CSS layout box is currently specified and compare it with the UA style rule approach. Done means the wording clearly defines the intended behavior and resolves whether the existing WebKit implementation conforms.
