title: Activiti lack of native rule engine support
body: <p>I'm doing some comparisons and a presentation tomorrow with different BPMS systems and I was reading about the difference between jbPM (the source engine that was used to build Activiti) and the Activiti engine. Can someone tell what is the caution of jBpm having the native built-in business Rules engine where Activiti has no native rule engine support but supports a basic integration with Drools to support the business Rule Task?</p>
  
  <p>This is a real important question for me so a quick response to this would be great. </p>
  
  <p>Thanks</p>
