+  <p>
+    This sample shows how to setup an <code>elementFinished</code> option for <a>Diagram.makeSvg</a> that will replace the
+    SVG <code>&lt;image&gt;</code> tag's <code>href</code> with a Base64 URI instead of pointing to the <a>Picture.source</a>.
+    This can be useful to reduce external dependencies within your exported SVG.

+    This method will only work if you assets are at the same origin,
