// @brief Configuration data structures and XML loader for the routing service.
//
// The on-disk format is a small XML schema that mirrors the OMG DDS routing
// service concepts while remaining implementation-agnostic and human-editable.
//
// Example:
//   <routing_service name="domain_bridge">
//     <domain_route name="bridge_0_to_5">
//       <participant name="input"  domain_id="0"/>
//       <participant name="output" domain_id="5"/>
//       <topic_route name="squares">
//         <input  topic="Square"   type="ShapeType"/>
//         <output topic="Square"   type="ShapeType"/>
//         <filter>color = 'RED'</filter>
//       </topic_route>
//     </domain_route>
//   </routing_service>
