<h3>Core Mediators</h3>
<h4><a name="send">Send</a></h4>
-<p>The send token represents a <send> element. The <send> element
-is used to send messages out of Synapse to some endpoint, and stop further
-mediation of the message. The send mediator also copies any message context
-properties from the current message context to the reply message received on
-the execution of the send operation. This allows the reply messages to be
-correlated to the original messages in a flexible manner. Messages may be
-correlated by WS-A MessageID, or even simple custom text labels. Also see the
-property mediator.</p>

-<p>In the simplest case, the place to send the message to is implicit in the
-message (via a property of the message itself)- that is indicated by the

+<p>The send token represents a <send> element, used to send messages
+out of Synapse to some endpoint. The send mediator also copies any message
+context properties from the current message context to the reply message
+received on the execution of the send operation so that the response could be
+correlated back to the request. Messages may be correlated by WS-A MessageID,
+or even simple custom text labels (see the property mediator and samples)</p>
+
+<p>In the simplest case shown below, the destination to send a message is
+implicit in the message via the 'To' address. Thus a request message will be
+sent to its 'To' address, and a response message would be sent back to the
+client. Removing the 'To' address of a message targets it back to the client,
+and thus a request message received may be returned to the client after
+changing its direction. (Note: to mark a message as a response set the
+property RESPONSE to true)</p>
+
+<p><strong>Note:</strong> A send operation may be blocking or non-blocking
+depending on the actual transport implementation used. As the default NIO
+based http/s implementation does not block on a send, care must be taken if
+the same message must be sent and then further processed (e.g. transformed).
+In such a scenario, it maybe required to first clone the message into two
