Following a post link in a recent retweet of yours, I came across a blog 
post [1] that contains this excerpt:

"...Assuming the data could be retrieved and the keys match, this tells 
the consuming service three things:

You have access to the corresponding private key (the TLS protocol 
exchange would have failed if not).

** Because the public keys in the certificate and profile document 
matched, any assertions made within the profile can be treated as being 
equivalent to if you made them as part of the certificate itself (and 
nobody else can make those assertions to you, because their public key 
wouldnít appear in the profile). **

Because the keys match, you have confirmed that you are able to publish 
information at the URI in your subjectAltName (you canít pick somebody 
elseís URI, because you donít have the private key corresponding to the 
public key in their profile). .."

I don't see how anyone wouldn't understand "mirrored claims" from the 
above. Assertions are made in two places that are semantically 
equivalent in human and machine discernible ways.

We are all endowed with the ability to describe the same concepts 
slightly differently based, on our backgrounds and target audiences. 
This capability ultimately makes the end product richer, especially when 
it brings others to the fold that would erstwhile not make obvious 

I am fundamentally interested in engaging as many communities as 
possible. My focus isn't external to the hard core Semantic Web and 
Linked Data communities, if it was I would speak in pure Semantic Web 
parlance -- which I can speak extremely fluently. Trouble is, there is a 
much broader audience that will benefit from WebID that remain of prime 
interest to myself and others, and as a result I speak (deliberately) in 
terms you and others (of the aforementioned Semantic Web and Linked Data 
profiles) may find alien.

I would like to believe that we are seeking a broader adoption pool for 
WebID, so let's not keep on distracting ourselves re. these matters.

If I felt WebID was a load of rubbish I wouldn't invest a second of my 
time on it. At the same time, when something truly matters, I believe in 
being ready to dish out "tough love."
