[Fwd: [Moderator Action] Patterns broken in Adobe SVG Viewer 3.0 Beta 4?]

attached mail follows:

The following SVG file displays fine in IBM SVGView v0.4a.
Adobe displays the rectangle but not the pattern.

Is the SVG pattern below incorrect, or is Adobe's viewer broken?

<?xml version="1.0" standalone="no"?>
<svg width="150" height="100" viewBox="0 0 150 100">
<defs>
  <pattern id="pat1" x="0" y="0" width="15" height="15">
    <rect width="15" height="15" style="fill:white"/>
    <path style="fill:none;stroke:black" d="M 0,7.5 L 15,7.5"/>
  </pattern>
</defs>
<rect style="stroke:red;fill:url(#pat1)"
   x="5" y="5" width="140" height="90"/>
</svg>
