Yeah; the current Tor specs do have a problem where they all kind of
assume that you've read all the other specs. That's one reason I

Right; I should add a reference to dir-spec at the appropriate place.

It's an identity digest as used in tor-spec: a SHA1 digest of the
node's RSA identity key. I should add a reference there too.
(See proposal 220 for the start of migrating keys away from RSA1024
and SHA1, though in this case I don't think that matters.)
