An SVG image that has a viewBox attribute and a non-percentage value for exactly one of the height or width attributes. It's reasonable to want to describe such an image as having both an intrinsic width and an intrinsic height, but if you want that to be the case, something should say so. (I'd suggest putting it in the definition of "intrinsic dimensions" in 5.1 (Object-Sizing Terminology).) -David -- 𝄞 L. David Baron http://dbaron.org/ 𝄂 𝄢 Mozilla http://www.mozilla.org/ 𝄂
