+ * <li>instanceCount: The number of Apex engines to spawn in this engine service. Each engine
+ * executes in its own thread.
+ * <li>deploymentPort: The port that the Apex Engine Service will open so that it can be managed
+ * using the EngDep protocol. The EngDep protocol allows the engine service to be monitored, to
+ * start and stop engines in the engine service, and to update the policy model of the engine
+ * service.
+ * <li>engineParameters: Parameters (a {@link EngineParameters} instance) that all of the engines in
+ * the engine service will use. All engine threads use the same parameters and act as a pool of
+ * engines. Engine parameters specify the executors and context management for the engines.
+ * <li>policyModelFileName: The full path to the policy model file name to deploy on the engine
+ * service.
+ * <li>periodicEventPeriod: The period in milliseconds at which the periodic event PERIOIC_EVENT
+ * will be generated by APEX, 0 means no periodic event generation, negative values are illegal.

+ * <li>eventProtocolParameters: The format that the events are in when being carried. Examples are
+ * JSON, XML, or Java Beans. carrier technology
+ * <li>synchronousMode: true if the event handler is working in synchronous mode, defaults to false
