/**
 * 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.
