+Retry Token:
+
+: An opaque token that the server can use to validate the client's address.
+
+The server populates the Destination Connection ID with the connection ID that
+the client included in the Source Connection ID of the Initial packet.
+
+The server includes a connection ID of its choice in the Source Connection ID
+field.  The client MUST use this connection ID in the Destination Connection ID
+of subsequent packets that it sends.
+
+A Retry packet does not include a packet number and cannot be explictly
+acknowledged by a client.
+
+A server MUST only send a Retry in response to a client Initial packet.

I prefer to leave this as SHOULD for now, but will open a new issue.  This wasn't the focus of this change (this is not my text), so let's have an explicit discussion about it.
