-The producer supports request/reply where it can wait for an expected reply 
message.
+The producer supports request/reply: when the exchange pattern is InOut, it 
waits for the reply message, up to
+`requestTimeout`, and the payload of the reply becomes the message body, as a 
byte array.
 
-The consumer will, when routing the message is complete, send back the message 
as reply-message if required.
+The consumer sends back the message body as the reply message, when routing 
the message is complete, if the message has a
+reply subject and the consumer has `exchangePattern=InOut`. The body must 
convert to a byte array: text, bytes, a stream or a
+file. A body that does not, such as a Map, sends no reply.

 === Request/Reply support
-The producer supports request/reply where it can wait for an expected reply 
message.
+The producer supports request/reply: when the exchange pattern is InOut, it 
waits for the reply message, up to
+`requestTimeout`, and the payload of the reply becomes the message body, as a 
byte array.
 
-The consumer will, when routing the message is complete, send back the message 
as reply-message if required.
+The consumer sends back the message body as the reply message, when routing 
the message is complete, if the message has a
+reply subject and the consumer has `exchangePattern=InOut`. The body must 
convert to a byte array: text, bytes, a stream or a
+file. A body that does not, such as a Map, sends no reply.
