Is there an public key and webid relationship in the final document that 
matches what's in the x.509 certificate used in the TLS handshake? The 
path doesn't determine the semantics of the pivotal relationship between 
a webid and public key.

As the owner of a WebID (a de-referencable URI) used to watermark an 
X.509 cert.  I control the route to the graph that validates my identity 
claims using the WebID protocol. That's what this protocol is about, 
semantically :-)
