/**
 * Support for transactions subsystem configuration updates.
 *
 * The special case for this subsystem:
 *
 * If [process-id-uuid] == true then:
 * - Do not send updates for [process-id-socket-binding], this property
 *   will be undefined by the AS7 on the next server reload/restart
 * - Do not send updates for [process-id-socket-max-ports], this property
 *   requires to be undefined on this case. EAP will assign 10
 *
 * If [process-id-uuid] == false then send [process-id-socket-binding] value, [process-id-socket-max-ports] value and
 * allow AS7 to perform property validation
