Well no wonder you can't get it to work in any browser, thats not
valid HTML, SVG isn't an image and can't be used with the img tag.
The example below shows the correct <object etc html, which works in
the few browsers I have access to and is reported to work in most
modern browsers.

As I said below you can hide the nasties by writing your own macro :)

The default is dblatex which doesn't support SVG at all.

Just include the following stolen from the image macro definition
</div>
<div class="title">{caption={figure-caption} {counter:figure-number}.
}{title}</div>
</div>
in your svg:: macro when you create it.
In fact its worthwhile looking at how images are created in the
docbook and xhtml backends and re-use as many ideas as are
appropriate.
