While it might sound trivial to allow 'transform' on the <svg> element, here are some things to consider:
The root <svg> is always special because it is involved in setting up the main viewport. If there was a transform attribute should it be applied after the viewBox transform or before? To me it sounds like the expectation in this thread was that it would be applied after the viewBox transform. That is counter-intuitive if you consider the case with nested <svg> elements. In those cases you'd likely want transform to be applied before the viewBox instead, making it more similar to a <g> element in a sense. Consider what would happen if you had <svg> inline in HTML and applied a CSS3 transform to rotate the svg element. It would rotate the <svg> viewport, which is what I would expect. Depending on how the viewer displays standalone svgs that might look weird (as in: some parts of the svg might end up outside the window). Anyway, if the purpose is to do panning, zooming and rotation dynamically then there are methods available on the SVGSVGElement interface (note: the SVGSVGElement.currentRotate attribute is only available in viewers that support SVG Tiny 1.2). If the purpose was to just do a rotation of the content and it's static, then go with the suggested <g> wrapper solution. Also see http://www.w3.org/Graphics/SVG/WG/track/issues/2252.
