Sections 3.1 and 3.3 -- please remove the hmac-algorithm.

The algorithm is a property of a key, not of an interface.  There's no
need to specify the algo here, it is determined by the set of configured
keys.  (And it is quite legal to use keys with different algos on the same
interface, for example when transitioning from one algorithm to
a different one.)

The second point is something we've discussed before.  The implementation
has the interface point at the set of keys; in the model, the key set
points at the interface.  Is the discrepancy intentional?
