          This memo describes a syntax for embedding S-HTTP negotiation
          parameters in HTML documents.  S-HTTP, as described by 
          <a href="http://suika.fam.cx/uri-res/N2L?urn:ietf:rfc:2660" title="RFC 2660">RFC 2660</a>, contains the concept of 
          negotiation headers which reflect the potential receiver of 
          a message's preferences as to which cryptographic enhancements 
          should be applied to the message. This document describes a 
          syntax for binding these negotiation parameters to HTML anchors.
