How do I know if my browser supports SVG 2.0?
(Apart from trying a feature that is supposed to work in SVG2 and realizing it\'s not working or that it works ...?)
Asking if a browser supports SVG 2 is like asking if a browser supports HTML5. It seems like a totally reasonable question, but it doesn't work like that.
The best we can do is test if a browser supports a feature, rather than a version of spec. As you can see from the SVG 2 Support in Mozilla page, it's a mixed bag.
