 On receiving a PATH_CHALLENGE frame, an endpoint MUST respond immediately by
 echoing the data contained in the PATH_CHALLENGE frame in a PATH_RESPONSE frame.
+An endpoint MUST NOT send more than one PATH_RESPONSE frame in response to one
+PATH_CHALLENGE frame (see {{retransmission-of-information}}).  A new
+PATH_CHALLENGE frame will be sent if another PATH_RESPONSE frame is needed.

Suggested rephrase: The peer is expected to send more PATH_CHALLENGE frames as necessary to evoke additional PATH_RESPONSE frames.
