So in summary:

 (1) most browsers currently understand the mime types 
     (a) application/x-x509-user-cert 
     (b) application/x-x509-ca-cert 
     (c) application/x-x509-email-cert
   ( I have only verified (a) btw. I am assuming the others also support (b) and (c) )
   as specified here
   https://wiki.mozilla.org/CA:Certificate_Download_Specification

  (2) the above mime types are not registered
     http://www.iana.org/assignments/media-types/media-types.xhtml
 
   So really either the old mime types should be registered, or they should be mentioned as being
 in use but deprecated and people should be guided towards the application/pkix-cert
