> -In this document, the TLS handshake is considered confirmed at an endpoint when
-the following two conditions are met: the handshake is complete, and the
-endpoint has received an acknowledgment for a packet sent with 1-RTT keys.
-This second condition can be implemented by recording the lowest packet number
-sent with 1-RTT keys, and the highest value of the Largest Acknowledged field
-in any received 1-RTT ACK frame: once the latter is higher than or equal to the

+A client MAY consider the handshake to be confirmed when it receives an

I agree. I think this should be "is".
