Pure composite baselines

Like all baselines, a composite baseline must belong to a component. However, that component does not need to contain any of its own elements. For example, in Using a system-level composite baseline, the System component, ProjA_Comp, and ProjB_Comp components consist only of their composite baselines. When you create a component to be used solely for housing a composite baseline, you can specify an option that directs UCM to make the component without creating a root directory in a VOB. Such a component can never contain its own elements and its baseline is referred to as a pure composite baseline.
