     * The following annotations contain a simple description of the expected

     * elements.
     * The strings contain a comma-separated list of descriptions.
     * Descriptions are composed as follows:
     * A leading "!:" indicates the type mirror has kind ERROR.
     * "empty" means that the corresponding element has no enclosed elements.
     * "clss", "intf" and "tvar" indicate the name refers to a class, interface
     * or type variable. Each is followed by the declared name of the element.
     * "pkg" indicates the name of a package element.
     * An enclosing element is shown in parentheses.
     * A trailing "!" indicates that the element's type has kind ERROR.
