[foaf-protocols] Why exponent/modulus

Hi All,

Similar to my previous question, why do we extract the modulus and 
exponent of a public key and represent those in RDF, if we were instead 
to store a PEM/DER encoded version of the public key, or even 
certificate, in our profiles instead, what would break?

With this specific question, the main background thinking is that 
implementations of WebID protocol would be much easier, with far less 
dependencies, if we did simply throw a PEM/DER certificate in to our 
profiles, all those Wordpress/Mediawiki/Drupal type plugins, and indeed 
support in any language which had basic support for HTTP+TLS would 
suddenly become a very easy hit.
