Default Gate property for Diverging Inclusive Gateway is not generating the jBPM5 expected output

The 'DefaultGateway' property of a Diverging Inclusive OR generates the following output:
<bpmn2:inclusiveGateway ... drools:dg="X" gatewayDirection="Diverging">

The expected format for jBPM5 should be:
<bpmn2:inclusiveGateway ... default="X" gatewayDirection="Diverging">

The problem here is not only the xml attribute being used but within the Designer the user should be able to set the id of the default workflow, which is something he doesn't know in advance. The editor for this property should show a list of all the outgoing flows of the gateway (maybe showing their names) so the user can easily select the one he wants.
