            Controls how JPA extended persistence context (XPC) inheritance is performed. 
            DEEP - Extended persistence context is shared at top bean level with all sub-beans referencing the same named persistence context.
            SHALLOW - Extended persistece context is only shared with the parent bean (never with sibling beans).
