@AndriySvyryd is this how we should configure self many to many? (i.e. the OnDelete part)

Entities: One, Two, Three - regular CompositeKey - entity with composite key Root, Branch, Leaf - inheritance Navigations (all many to many have corresponding navigation on the other side that is not listed here): One - TwoFullySpecified - ThreeFullySpecifiedWithPayload - TwoSharedType - ThreeSharedType - SelfSharedTypeWithPayload - BranchFullySpecified Two - ThreeFullySpecified - SelfFullySpecified - CompositeSharedType Three - CompositeFullySpecified - RootSharedType Composite - RootSharedType - LeafSharedType For now shared type scenarios are not supported in metadata API so we added linking entities temporarily. Those should be removed once the support is in.
