Deprecating (or dropping) 'enable-background' would essentially mean that BackgroundImage and BackgroundAlpha would always generate a transparent black result in the context of filters (I presume this is what the browsers that don't support enable-background already do, and it follows the error handling that is defined for when there was no "enable-background:new" parent element). Typically that means that things still render without errors but probably not as intended by the author. I think that we'd still need to keep some wording there to say what 'enable-background' is/was for the BackgroundImage/BackgroundAlpha cases, but I'd prefer to keep it short and to link to SVG 1.1 for the full definition. How does that sound? /Erik On Tue, 26 Apr 2011 02:50:11 +0200, Dean Jackson <dino@apple.com> wrote: > What does this mean for existing content that uses 'enable-background'? > I doubt there is much of it, but still, there are a couple of existing > recommendations that define it.
