bug in cert.n3

I think I have found a bug in the cert ontology at

http://www.w3.org/ns/auth/cert.n3

:privateExponent
   rdfs:domain :RSAPrivateKey;

Is used yet :RSAPrivateKey is nowhere defined

The correction should be:

:RSAPublicKey a owl:Class;
    rdfs:label "RSA Private Key"@en;
    rdfs:isDefinedBy <cert#>;
    rdfs:subClassOf :PrivateKey, :RSAKey;
    vs:term_status "unstable";
    rdfs:seeAlso <http://en.wikipedia.org/wiki/RSA>;
    rdfs:comment """
    The RSA private key.  Padded message m are encrypted by applying the
function
      modulus(power(m,exponent),modulus)
    """@en .

I have raised issue 77 to address this

https://www.w3.org/2005/Incubator/webid/track/issues/77

Please let me know if/how I can help action this fix
