>>> [Qi] A new type of relay message targets at the relay agent. If a relay agent recognizes the message, then it should consume the message. Otherwise, the relay just sends the message to the server (in a Relay-forward message), so that the server gets the information that this relay doesn't support the new relay agent message.

IMHO, that is much better. In the former case, the verb "send" makes
it ambiguous - message sent to a relay agent doesn't have to be
necessarily consumed/processed by relay, it could be forwarded. At
least this is how I read it. :-)
