The authoritative version of the hCard is only going to be relative
to the published hCard itself. The situation doesn't change. Someone
could already write an inaccurate hCard for me on their website. They
could write a more thorough version and link from one to the other
with rel="me self". This addition doesn't affect the authenticity.
Authenticity falls out of scope of hCard alone. Layer in some OpenID
and you can have start to imply some authenticity. (e.g. Parse an
hCard at the OpenID url and follow rel="me self" to another domain.)
If you mean, someone at ‘BenWardSmellsAwful.com’ (don't register
that, please) writing an hCard and linking to ben-ward.co.uk/about
with rel="self me", the relationship is such that the Fake Ben's
hcard is discarded in favour of my real one. This does not allow
someone to describe ‘this hCard here is the authoritative version of
that one over there’. The direction of parsing disallows fakes.
