-/**
- * @group Polymer Core Elements
- *
- * The `core-iconset-svg` element allows users to define their own icon sets
- * that contain svg icons. The svg icon elements should be children of the
- * `core-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:
- *
- *     <core-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>
- *     </core-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
- * `core-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 core-iconset-svg
- * @extends core-meta
- * @homepage github.io
