And emailAddress is not an Address either right?
What do you think www.freesoft.org is then?

We are using a standard representation of an info card and its 
semantics, to construct a protocol with its own set of semantics i.e., 
the WebID verification protocol. Nothing that I've stated breaks 
anything re. X.509 or PKI. Neither does it break WebID. Its only issue 
is novelty.
