well, this is tricky, because the goal here is to provide a global
bibliographic database, which means that we don't want the anchor to be
conflict with something else.
    
i suppose there are possibilities:
    
    - leave the anchor alone have the amount of indentation be specific
      to each reference.
    
    - provide a way of mapping the anchor strings within the main
      document, e.g.,
    
        <?rfc anchormap='%I-D\.ietf-(*)%\1%'?>
    
      which would give you
