I don't know if this is any better or worse, but I acomplish this
same idea (I think) by editing the SVG DOM...

In the SVG file are the icons which are just invisible nodes defined
inside the <defs> tag and having "id" attributes with known values.

Then, using the DOM API, I add append a new <use> to the top level
<svg> tag like this:

    SVGElement topNode = ...	// find the top <svg> node
    String iconId = ...		// id of the icon you want to display
    SVGElement use = (SVGElement)svg.createElementNS(
	SVGDOMImplementation.SVG_NAMESPACE_URI, "use");
    use.setAttributeNS(XPATH_NAMESPACE_URI, "href", "#" + iconId);
    use.setAttribute("visibility", "visible");
    use.setAttribute("x", "" + x);
    use.setAttribute("y", "" + y);

You must do this within this update thread (I think).
