Re: X.509 and PGP

Hi Jeremy,

I just had a look at the XML DigSig Spec
(http://www.w3.org/TR/xmldsig-core/).
Interesting document, containing all we need:

1.  Signature Data Model and Syntax.
XML-signature data structures must be based on the RDF data model [RDF] but
need not use the RDF serialization syntax.

2. Signeture RDF Data Model
http://www.w3.org/TR/xmldsig-core/xmldsig-datamodel-20000112.gif

3. They definded URI for the relevant signeture and digest methods. e.g.
http://www.w3.org/2000/09/xmldsig#sha1 or
http://www.w3.org/2000/09/xmldsig#rsa-sha1

I didn't find a RDF Schema yet, only a DTD. So when your are done with the
next version of the vocabulary, it will be easy to replace the relevant swp:
terms with xml-sig: terms.
