+@group Polymer Core Elements
+
+`core-animation-group` combines `core-animation` or `core-animation-group` elements to
+create a grouped web animation. The group may be parallel (type is `par`) or sequential
+(type is `seq`). Parallel groups play all the children elements simultaneously, and
+sequential groups play the children one after another.
+
+Example of an animation group to rotate and then fade an element:
+
+    <core-animation-group type="seq">
+      <core-animation id="fadeout" duration="500">
+        <core-animation-keyframe>
+          <core-animation-prop name="transform" value="rotate(0deg)"></core-animation-prop>
+          <core-animation-prop name="transform" value="rotate(45deg)"></core-animation-prop>
+        </core-animation-keyframe>
+      </core-animation>
+      <core-animation id="fadeout" duration="500">
+        <core-animation-keyframe>
+          <core-animation-prop name="opacity" value="1"></core-animation-prop>
+        </core-animation-keyframe>
+        <core-animation-keyframe>
+          <core-animation-prop name="opacity" value="0"></core-animation-prop>
+        </core-animation-keyframe>
+      </core-animation>
