The WebID should be a URI which when dereferenced returns a representation whose description uniquely identifies the Agent who is the controller of a public key. In our example the WebID refers to Bob. A WebID is usually a URL with a #tag, as the meaning of such a URL is defined in the document refered to by the WebID URL without the #tag .

Dereferencing the WebID should return the Profile Page in one of a number of formats. The Server must publish the document in at least the RDFa [RDFA-CORE] serialization format or in Turtle [TURTLE-TR]. The document may be published in a number of other RDF serialization formats, such as RDF/XML [RDF-PRIMER], or N3 [N3]. Any other serializations that intend to be used by the WebID Protocol must be transformable automatically and in a standard manner to an RDF Graph, using technologies such as GRDDL [GRDDL-PRIMER].

My problem with this definition is that we now need to define a special type of WebID Profile for WebID over TLS, since in the WebID over TLS spec we need the profile document to contain a public key.
