Re: Properly implementing <switch> with <foreignObject>

After fiddling for a while here I've figured out a way to at least test whether the browser supports foreignObject. This is done by using the "requiredFeatures" attribute rather than "requiredExtensions" like so:


<switch>
  <foreignObject width="100" height="50" requiredFeatures="http://www.w3.org/TR/SVG11/feature#Extensibility">
    <!-- whatever external user-agent stuff -->
  </foreignObject>

  <!-- Alternate SVG content if foreignObject is not supported -->
</switch>

This isn't perfect as the user-agent may not support the namespace that you attempt to use even though it supports foreignObject. However, I think it's safe to assume that, if the user-agent supports foreignObject, it will at least support XHTML and MathML.
