Hi Thomas,
I do not understand what you mean, the attached svg source contains an
'svg' element.
For completeness, here's the source again:
<svg:svg
viewBox="0 0 100 100"
width="100"
height="50"
xmlns:svg="http://www.w3.org/2000/svg";
xmlns:xlink="http://www.w3.org/1999/xlink";>
<svg:defs>
<svg:polygon id="Star" points="-4,-1 -1,-1 0,-4 1,-1
4,-1 2,1 3,4 0,2 -3,4 -2,1"/>
</svg:defs>
<svg:rect width="100" height="100" x="0" y="0" fill="yellow"/>
<svg:use x="50%" y="50%" xlink:href="#Star"
style="fill:limegreen;stroke:black;stroke-width:0.7px;"/>
</svg:svg>

Every SVG fragment must have an 'svg' element to define the
SVG viewport. 99% cetain This is your problem.
