Remarks
The meaning of the relationship surrogate is that the composed element is really the same logical entity as the composing element, but it is used in order to enable polymorphism and arbitrary cardinality for only a portion of the outer object. From the ModelStore perspective, ComposingRelationshipSurrogate and Composing are equivalent. However, clients of a ModelStore should interpret a ComposingRelationshipSurrogate child as being the same object as the containing element, whereas, in the Composing case, the inner element is a subobject.
