RFC 2659              Security Extensions For HTML           August 1999


        [SHTTP]. Specifically, the  production.

2.1.  CERTS Element

   A new CERTS HTML element is defined, which carries a (not necessarily
   related) group of certificates provided as advisory data. The element
   contents are not intended to be displayed to the user. Certificate
   groups may be provided appropriate for either PEM or PKCS-7
   implementations. Such certificates are supplied in the HTML document
   for the convenience of the recipient, who might otherwise be unable
   to retrieve the certificate (chain) corresponding to a DN specified
   in an anchor.

   The format should be the same as that of the 'Certificate-Info'
   header line, of [SHTTP] except that the  specifier should
   be provided as the FMT attribute in the tag.

   Multiple CERTS elements are permitted; it is suggested that CERTS
   elements themselves be included in the HTML document's HEAD element
   (in the hope that the data will not be displayed by S-HTTP oblivious
   but HTML compliant browsers.)

2.2.  CRYPTOPTS Element

   Cryptopts may also be broken out into an element and referred to in
   anchors by name. The NAME attribute specifies the name by which this
   element may be referred to in a CRYPTOPTS attribute in an anchor.
   Names must have a # as the leading character.

2.3.  HTML Example

   An example of cryptographic data embedded in an anchor, proceeded by
   a certificate group is provided below. Note the SGML quoting syntax
   used to supply embedded quotation marks.
