            <documentation>The 'show' attribute is used to communicate the desired presentation 
        of the ending resource on traversal from the starting resource; it's 
        value should be treated as follows: 
        new - load ending resource in a new window, frame, pane, or other 
              presentation context
        replace - load the resource in the same window, frame, pane, or 
                  other presentation context
        embed - load ending resource in place of the presentation of the 
                starting resource
