          <meta name="cover" content="-reference to a manifest item-">
          Then, we also added a bit of logic to get rid cleanly of the HTML cover
          people usually add because the logical cover is not specced by the IDPF. So,
          if the HTML cover item is marked linear="no" AND there is a guide item of
          type="cover" pointing to it AND there is a logical cover specified in a
