+/**
+ * The `iron-iconset-svg` element allows users to define their own icon sets
+ * that contain svg icons. The svg icon elements should be children of the
+ * `iron-iconset-svg` element. Multiple icons should be given distinct id's.
+ *
+ * Using svg elements to create icons has a few advantages over traditional
+ * bitmap graphics like jpg or png. Icons that use svg are vector based so
+ * they are resolution independent and should look good on any device. They
+ * are stylable via css. Icons can be themed, colorized, and even animated.
+ *
+ * Example:
+ *
+ *     <iron-iconset-svg name="my-svg-icons" size="24">
+ *       <svg>
+ *         <defs>
+ *           <g id="shape">
+ *             <rect x="12" y="0" width="12" height="24" />
+ *             <circle cx="12" cy="12" r="12" />
+ *           </g>
+ *         </defs>
+ *       </svg>
+ *     </iron-iconset-svg>
+ *
+ * This will automatically register the icon set "my-svg-icons" to the iconset
+ * database.  To use these icons from within another element, make a
+ * `iron-iconset` element and call the `byId` method
+ * to retrieve a given iconset. To apply a particular icon inside an
+ * element use the `applyIcon` method. For example:
+ *
+ *     iconset.applyIcon(iconNode, 'car');
