Re: problem with animateMotion in element

Hi Andreas.

Andreas Neumann:

This example now works with the code in SVN:

  <svg xmlns="http://www.w3.org/2000/svg";
       xmlns:xlink="http://www.w3.org/1999/xlink";>
    <defs>
      <svg id="s" viewBox="0 0 100 100">
        <circle cx="0" cy="0" r="100"/>
      </svg>
    </defs>
    <use xlink:href="#s" width="100" height="100">
      <animate attributeName="width" dur="5s" from="0" to="100"/>
    </use>
  </svg>

This too:

  <svg xmlns="http://www.w3.org/2000/svg";
       xmlns:xlink="http://www.w3.org/1999/xlink"; font-size="20">
    <defs>
      <circle id="c" cx="0" cy="0" r="100" fill="blue" opacity="0.5">
        <animate id="a" attributeName="r" dur="5s" from="0" to="50"
                 fill="freeze"/>
      </circle>
    </defs>
    <use xlink:href="#c" x="100" y="100"/>
    <use xlink:href="#c" x="200" y="100"/>
    <use xlink:href="#c" x="150" y="150"/>
    <text x="150" y="141" fill="white" display="none"
          text-anchor="middle">
      <set attributeName="display" begin="a.end" to="inline"/>
      a.end
    </text>
  </svg>

This definitely doesn’t work at the moment:

  <defs>
    <g id="g"/>
  </defs>
  <use xlink:href="#g"/>
  <animate xlink:href="#g" …/>

This is because internally used elements are handled by cloning the
subtree.  The first other example works only because the 'animate'
element gets cloned along with it.  At some point 'use' will have to be
re-engineered to handle this (and also implement the .instanceRoot and
.animatedInstanceRoot attributes).
