When viewing the SVG below, the red rectangle should disappear at 3s.

The red rectangle is referenced by a <use>.
The <use> is contained inside a <g>. 
The visibility of the <g> is set to hidden at 3s.

<svg width="100%" height="100%" viewBox="0 0 1000 800"
  xmlns="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org/1999/xlink">
  <defs>
    <rect id="r" x="100" y="100" width="800" height="600" fill="red" stroke="none"/>
  </defs>
  <g>
    <use xlink:href="#r"/>
    <set attributeType="XML" attributeName="visibility" to="hidden" begin="3s"/>
  </g>
</svg>

Works with Safari 4.0.5 (531.22.7), Windows XP
Doesn't work with
  Chrome 7.0.517.44, Windows XP
  Safari 5.0.3 (6533.19.4), Mac OS X 10.6

A subsequent browser Zoom causes the red rectangle to disappear.

The <set> animation does work when directly targeting the <use>

  <use xlink:href="#r">
    <set attributeType="XML" attributeName="visibility" to="hidden" begin="3s"/>
  </use>
