one may either, with namespaces,  use code that looks like:
<circle cx="10" cy="300" r="1" >
<svgr:random attributeName="cx" min="0" max="300" />
<svgr:replicate repeatCount="1000" />
</circle>
or without namespace declarations like:
<circle cx="10" cy="300" r="1" >
<random attributeName="cx" min="0" max="300" />
<replicate repeatCount="1000" />
</circle>
