Nelson;
   In collecting data for this reply, I found that you are correct.
On the screen are two links (so to speak). One is an Address Card
icon and the other is a "Download" link. The link has a number of LDAP
args and ends with the "application/x-x509-email-cert" mime type.

But I will include the specifics anyway. These certs do raise some
questions.

  URL=https://ds-web.c3pki.chamb.disa.mil/dsgw/bin/lang?context=dsgw-mail
  "Standard Search"
  "wojcik"     as search arg
  Pick 3rd entry (Not LRA or RA)
  Click "Download Certidficate".
  Nothing changes on the screen, no pop-up, but cert is loaded.
  Clicking the Address card in Mozilla gives you a download that
    Mozilla doesn't know how to handle, where as Netscape presents
    a popup and a simple display.

  Examining the Cert shows:
    Index has Name and email address.
    Detailed view failes to show email (in recognizable form).
    BUT under extensions is OID 2 5 29 17 (subAltName)
      is a hex string with his email address

  Obviously some piece of code could read this extension, because
  the email address came from it.
