- /** |
- * Support `extends` property (for type-extension only). |
- * |
- * If the mixin is String-valued, the corresponding Polymer module |
- * is mixed in. |
- * |
- * Polymer({ |
- * is: 'pro-input', |
- * extends: 'input', |
- * ... |
- * }); |
- * |
- * Type-extension objects are created using `is` notation in HTML, or via |
- * the secondary argument to `document.createElement` (the type-extension |
- * rules are part of the Custom Elements specification, not something |
- * created by Polymer). |
- * |
- * Example: |
- * |
- * <!-- right: creates a pro-input element --> |
- * <input is="pro-input"> |
- * |
- * <!-- wrong: creates an unknown element --> |
- * <pro-input> |
- * |
- * <script> |
- * // right: creates a pro-input element |
- * var elt = document.createElement('input', 'pro-input'); |
- * |
- * // wrong: creates an unknown element |
- * var elt = document.createElement('pro-input'); |
- * <\script> |
- * |
- * @class base feature: extends |
