Hi,

After an IRC discussion today on how USE elements should be handled if
the referenced DOM changes, does the use element also change, it was
decided it does.  This led to a problem with external references, to
included document, consider:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20010904//EN"
  "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">
<svg width="10cm" height="3cm" viewBox="0 0 100 30"
     xmlns=http://www.w3.org/2000/svg
 xmlns:xlink="http://www.w3.org/1999/xlink">
  <desc>Simple USE demo</desc>
  <rect x=".1" y=".1" width="99.8" height="29.8"
        fill="none" stroke="blue" stroke-width=".2" />
  <use x="20" y="10" xlink:href="foo.svg#MyRect" />
<image xlink:href="foo.svg" id="one"/>
<image xlink:href="foo.svg" id="two"/>
</svg>

If MyRect is changed in the image one, then does the referenced use
change aswell? as it's not been changed in two, which instance takes
precedence?

Jim.
