I have managed to narrow down this problem. Those of you who know SVG
better than I
will have known all along that the required SVG for this problem is
trivial:
<svg><text>...</text></svg>
I didn't spot that because I was using Inkscape, which adds - amongst
other things - a height
and a width to the <svg> element.
So I can proceed to the next problem, which is that the SVG
serializer for Cocoon renders
the SVG with apparently arbitrary widths, but that's a problem for a
different list.
