How to switch SOAP endpoints dynamically at runtime for SOAP reference bindings in SwitchYard

Issue

• We are implementing a Camel Java route as a service implementation and SwitchYard gateway reference with SOAP binding, acting as a SOAP client, which is being called by the Camel route.
• In switchyard.xml the SOAP endpoint address can be set like below. Here soap:endpointAddress is using a composite property.

<sca:reference name="someRef" multiplicity="0..1" promote="CamelServiceRoute1/MyService">
  <sca:interface.java interface="com.example.switchyard.ws.MyService"></sca:interface>
  <soap:binding.soap name="soap1">
    <soap:wsdl>wsdl/MyService.wsdl</soap:wsdl>
    <soap:wsdlPort>MyServicePort</soap:wsdlPort>
    <soap:endpointAddress>${ref-soapendpoint}</soap:endpointAddress>
  </soap:binding.soap>
</sca:reference>
...
<sca:property value="http://localhost:8080/context/MyService" name="ref-soapendpoint"></sca:property>

• In our requirement the endpoint ("http://localhost:8080/context/MyService") varies for each message. During the routing of each message, we need to retrieve the endpoint from a database and set the same as SOAP endpoint address.
• How can we override / set the endpoint address for each message at runtime?
