-  /**
-   * 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 id="my-svg-icons" iconSize="24">
-   *       <svg>
-   *         <defs>
-   *           <g id="shape">
-   *             <rect x="50" y="50" width="50" height="50" />
-   *             <circle cx="50" cy="50" r="50" />
-   *           </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');
-   *
-   * @element iron-iconset-svg
