Now this doesn't work with these escaping.

+
+        Element figure = Document.get().createElement("FIGURE");
+        figure.setInnerHTML(super.generateOutput(false));
+        if (!figCaption.isEmpty()) {
+            Element caption = Document.get().createElement("FIGCAPTION");
+            caption.setInnerHTML(figCaption);
+            figure.appendChild(caption);
+        }
+        DomUtil.makeAllLinksAbsolute(figure);
+        return figure.getString();
+    }
+}
