making svg content keyboard focusable

Hi Doug,

I have been looking at SVG a bit and trying to work out how to make a shape
keyboard focusable.

for example using a link: works in IE not in firefox (windows):

<svg width="5cm" height="3cm" viewBox="0 0 5 3"
     xmlns="http://www.w3.org/2000/svg">
  <desc>Example link01 - a link on an ellipse
  </desc>
  <rect x=".01" y=".01" width="4.98" height="2.98"
        fill="none" stroke="blue"  stroke-width=".03"/>
  <a xlink:href="http://www.w3.org">
    <ellipse cx="2.5" cy="1.5" rx="2" ry="1"
             fill="red" />
  </a>
</svg>

I thougfht maybe that addtion of tabindex could make it work:

<rect x=".01" y=".01" width="4.98" height="2.98"
        fill="none" stroke="blue"  stroke-width=".03" tabindex="0" />

but it dosn't

can you point me to any examples/ documents that provide clear info on how
to do it?
