Oh. Well, that explains a lot. But that doesn't seem to completely
solve the problem. When I do that, I get a new error:
org.jibx.runtime.JiBXException: Expected
"{http://www.w3.org/2000/svg}g"; start tag, found
"{http://www.w3.org/2000/svg}defs"; start tag (line 6, col 9)

Changed mapping for SVGRoot:
<mapping name="svg" class="svg.elements.SVGRoot"
extends="svg.elements.Graphic">
<structure map-as="svg.elements.Graphic"/>
<value name="viewBox" field="viewBox" style="attribute" usage="optional"/>
</mapping>
Do I have to do something to make it an anonymous map-as?
