Ah, ok.

The binding key is not used for headers exchanges; the matching
critieria are expressed in the arguments table that is passed to the
basic.bind method (most client libraries make this an optional parameter
to the bind call; see the docs for the client library you are using to
see how it gets exposed).

I'm afraid that I don't recall a description of header exchanges that is
better than the one in the AMQP 0-9-1 spec.  Though that section
(3.1.3.4) is quite readable and short (half a page), and if you are
familiar with RabbitMQ concepts you won't have to read the rest of the
spec to understand it.
