Actually I think this element would mean "start" on deployment as well as
"start" on engine startup or we can have two elements if more fine grained
control is required.

Maciej,

I would like to get a bit of clarification on this. Does BpelServer.deploy(File)
always imply a BpelServer.startDeploymentUnit(File) or should we add an
element into the DD that allows "start" on deployment to be specified?
