- * Validates name/value pairs in param tags to be used in safe objects. This
- * will only allow name values it recognizes, and pre-fill certain attributes
- * with required values.
- *
- * @note
- *      This class only supports Flash. In the future, Quicktime support
- *      may be added.
- *
- * @warning
- *      This class expects an injector to add the necessary parameters tags.
