is santizing SVGs hard, or just everyone forgets they can contain js?
I guess the next step is to propose a simple "noscripting" attribute, which if present in the root of the SVG doc inhibits all scripting by conforming renderers. Then the renderer layer at runtime could also take a noscripting option, so the rendering context could force it if appropriate. Surely someone at HN is on this committee, so see what you can do!
Edit: thinking about it a little more - maybe it's best to just require noscripting as a parameter to the rendering function. Then the browsers can have a corresponding checkbox to control SVG scripting and that's it.
i wonder do people not do this with svgs?
Sanitizing is hard to get right by comparison (svgs can reference other svgs) but it's still a good idea.
Firefox has this: svg.disabled in about:config. It doesn't seem to be properly documented, and might cause other problems for the developer (I found it accidentally, and a more deliberate search turns up mainly bug tracker entries.)
