As I see it, all data is a representation of the state of some resource.

PUT just prescribes that the provided representation is to be
interpreted as a representation of the desired state of the resource
identified in the HTTP request line.  It's not special in its ability
to transfer representations.

Consider that I could script a couple of HTTP messages that set the
state of a lightbulb to the same state of some other lightbulb, but in
the second message - the PUT request - the provided representation is a
representation of the state of the first lightbulb.  Not until the PUT
request succeeds is it also a representation of the second bulb.
