  Dear Sir./Miss.:
          I suggest add a tag to html, then we can add a signature to an HTML file.
  <sig name="adez" email="adez@21cn.com"  method=pgp >

  </sig>

  the digest of the message is caculate from the begin of the file to the last non-white pace char.
  and so an HTML can be signed by several peoples.
