There are many XXXs and RDs in prop224 that need to be addressed. The montreal hackfest is a good time for design changes.

Please see my branch prop224-montreal for some changes.

Specifically:

• We address many XXXs, TODOs and the recently introduced RDs in prop224.
• We do cross-certification of introduction point keys.
• We clarify various parts of the proposal (crypto, and legacy cells)
• Bump the key len in cells to 2 bytes.
• Add a ToC.
• Various other fixes.

-        "auth-key" SP "ed25519" SP certificate NL
+        "auth-key" SP "ed25519" NL certificate NL

"a RSA signature" -> "an RSA signature"

arma's comments are fixed by bca05ca2 on my prop224-montreal branch.

These spec changes got merged to torspec.git during the montreal hackfest.

More spec changes remain to be written, like the time period stuff. I'll update the [tor-dev] mailing list when these changes are ready.
