Human Tasks : Assign both users and groups in a single people assignment

Usual method of people assignment in WS Human tasks is using a logical people group. But it is not possible to assign to both people groups and users in a single logical people group. So in order to achieve this, you need to use literals as defined in WS Human Task Spec.

Following is a sample of assigning both groups and individuals inside same people assignment to potential owners. I have used and tested this in latest WSO2 Business Process Server successfully.
