+    <title>Enveloped tree</title>
+    <!-- 
+    PURPOSE: This test case is the reverse of the promoted tree case. As time
+    containers are defined relative to the outermost SVG document fragment this
+    case tests that when an outermost <svg> fragment is added as a child of
+    another svg document fragment, the animations behave correctly and the time
+    containers are resolved correctly.
+
+    OPERATION: There are two animations that are more-or-less identical except
+    for a few aesthetic features. Both contain a circle that moves to the right.
+    The second document fragment (on the right) is removed and added as a child
+    of the first document fragment.
+
+    EXPECTED RESULTS: After combining the two document fragments the circles
+    should have the same horizontal position as they are now controlled by the
+    same time container.
