It would be a straight multiplier to the alpha of the pixels, just like how (i think) it is now except you could also make something 'more' opaque than normal. This would be useful for say blurred objects that became too transparent.
I am pretty sure this would invalidate the css according to w3c but isn't that why there is inkscape-svg and plain-svg? When saving to plain-svg a file with something like 250% opacity, it could be layered like 2 100% objects and a 50% object which I believe would then be ok.
Thanks, Kevin
