Yes, that message from John Cowen is an excellent illustration of the
fact that it only reliably makes sense to talk about the semantics
(read: "GRDDL results") of a *representation* -- not an information
resource.  Indeed, two representations may have very different
semantics.  Such a situation would conflict with the WebArch:
http://www.w3.org/TR/webarch/#p139
[[
representation providers must not use content negotiation to serve
representation formats that have inconsistent fragment identifier
semantics. This situation also leads to URI collision 
]]
However, it could indeed occur, and it is important to be able to
clearly say: "The semantics of representations A and B are correct, but
the semantics of representation C are wrong".
