You may be right, but could you explain why those three should use companed sRGB rather than a light-linear space for computation? (And you are correct that the 'color-interpolation-filters' property should either be directly supported in the shorthand syntax, or alternatively each shorthand should state what the effective value of 'color-interpolation-filters' is - as well as giving the equivalent element-based filter syntax that corresponds to the shorthand. -- Chris Lilley Technical Director, Interaction Domain W3C Graphics Activity Lead, Fonts Activity Lead Co-Chair, W3C Hypertext CG Member, CSS, WebFonts, SVG Working Groups
