/**
* //TODO support endpoints, failover and loadbalacing
*
* The <send> element is used to send messages out of Synapse to some endpoint. 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 following
* <pre>
* <send/>
* </pre>
*
* If the message is to be sent to one or more endpoints, then the following is used:
* <pre>
* <send>
* (endpointref | endpoint)+
* </send>
* </pre>
* where the endpointref token refers to the following:
* <pre>
* <endpoint ref="name"/>
* </pre>
* and the endpoint token refers to an anonymous endpoint defined inline:
* <pre>
* <endpoint address="url"/>
* </pre>
* If the message is to be sent to an endpoint selected by load balancing across a set of endpoints,
* then it is indicated by the following:
* <pre>
* <send>
* <load-balance algorithm="uri">
* (endpointref | endpoint)+
* </load-balance>
* </send>
* </pre>
* Similarly, if the message is to be sent to an endpoint with failover semantics, then it is indicated by the following:
* <pre>
* <send>
* <failover>
* (endpointref | endpoint)+
* </failover>
* </send>
* </pre>
