Condition on sequence flow

I have read some example from user guide page. Those cases like the following case: <sequenceFlow id="endFlow1" sourceRef="exclusiveGw" targetRef="theEnd"> [b]<conditionExpression xsi:type="tFormalExpression">${loanRequest.approved}</conditionExpression>[/b] Are

Now I defined a flow which all node are usertask.
After each user task node, there are serveral outgoing sequence flows.
Something like the following graph.

In other words, I want to uniform those condition.

Thanks for you reply.

Yes, yesterday I have found those code in BPMNParser.java .
Currently, I just use other plan to realize my target.
