I'm not sure I agree. I think for security reasons, we should tell implementors how to treat SVG icons (no script, no interactivity). They won't have to strip down the SVG viewer, just set up constraints (which they need to do anyway). >> My recommendation is that you include normative references not only to >> SVG Tiny 1.1, but also SVG Full 1.1 (which is largely implemented in >> desktop browsers, and probably has the most current implementations), >> and SVG Tiny 1.2 (which is the most recent SVG Rec, and is deployed most >> widely on mobiles). ... >> particular needs and use cases, but in the meantime, I think the best >> thing would be to outline what capabilities should and should not be >> allowed for presenting an SVG icon.

I reviewed the spec a bit more, and didn't see any gotchas. Regards- -Doug Schepers W3C Team Contact, SVG and WebApps WGs
