Any extend symbol in Activiti but don't have in BPM?

[nhhao1996]

Hi everyone!

I'm researching about Activiti, I've read in User Guide and found something like Camel Task, Mule Task,... it said that it's not an official task of the BPMN 2.0.

So I want to know that what it's mean and any thing in Activiti but don't have in BPM? 

Thank you!

The concept of the Mule and Camel Tasks are essentially pre-built reusable Service Tasks.  So the Service Task is the standard BPMN 2.0 Activity Type and then the Mule and Camel are specific types of Service Tasks. The resulting BPMN XML is still compliant with the BPMN 2.0 specification. Hopefully, that helps.
