A test stream to stabilize a baseline

The integration stream has baselines PA.BL0, PA.BL1, PA.BL2, and PA.BL3. A child stream D1 is configured with baseline PA.BL0 and has some activities. A test stream DS is configured with a subsequent baseline PA.BL1. In the test stream DS, a new baseline PA.BL1.S is created and delivered to the integration stream. The child stream D1 then rebases to baseline PA.BL1.S to acquire the tested changes and to facilitate delivery of its activities to the integration stream.
