The z-index SVG 2 requirement is assigned to Tab: http://www.w3.org/Graphics/SVG/WG/wiki/SVG2_Requirements_Commitments Hasn't been added to the spec yet, though. As for SVG 1.1, I don't think it's a good use of time to update that document to define stacking contexts; let's just do it in SVG 2 itself. Defining which features cause stacking contexts to be created in SVG is most of the work for defining how z-index works anyway, so if you (Dirk or Rik) wanted to do that, I'd say feel free to.
