    <meta name="assert" content="The clipPath element takes the basic shape 'polygon' for clipping.
        The point list for the polygon creates a 'whole' with the dimension of the background. With
        the clip rule 'evenodd', this whole is clipped out. The clipping makes the green background
        of the parent div box visible.
        On pass you should see a green box with a blue border.">
