If you're still unconvinced of SVG's capabilities, this should convince you (requires Adobe's SVG Viewer 3.0). Notice the customised Context-Menu.

Reminds me of a friend's favourite gag:

Him: What's your favourite Ultravox song?

You: Vienna?

Him: It means nothing to me...

I fall for it every time. Don't worry if that makes no sense at all - that's probably a good thing!
