Paper

Hi guys,
I am writing a Paper on Open Source Workflow Engines(WE). Can you tell me if your WE can support the Control-Flow Patterns described under http://www.workflowpatterns.com/patterns/control/ ? If you are not sure, can you provide a Getting Started Doc or an Example for a  simple Sequence Workflow, so i can try to check it myself? 
thank you,
Silviu
