[css3-images] July F2F minutes comment regarding SVG and non-opaque colors

http://lists.w3.org/Archives/Public/www-style/2011Aug/0072.html

   shepazu: At the outset of this effort, there was discussion about remaining
            compatible with SVG  gradients.. was that abandoned?
   TabAtkins: No. SVG doesn't have alpha colors.


   * ed wonders what this meant: "TabAtkins: No. SVG doesn't have alpha colors."

        (most if not all browsers already support rgba/hsla syntax in svg

        colors/gradients, also there's stop-opacity in svg gradients)


I just happened to notice the commentary above.

I believe Tab was referring to this:
http://www.w3.org/TR/SVG/color.html
which links to <color> here:
http://www.w3.org/TR/SVG/types.html#DataTypeColor
which says

# The basic type <color> is a CSS2 compatible specification for a color in the sRGB color space [SRGB<http://www.w3.org/TR/SVG/refs.html#ref-SRGB>].



In short SVG 1.1's <color> maps to CSS2 (which does not include rgba and hsla) rather than CSS3 (which does).
