> enhance the Type system to allow entities to be created in parent child hierarchies. 
> I notice that AttributeDefinition currently only support  COLLECTION, SET , OPTIONAL and REQUIRED. There is no collection with a lower bound of 0- which would be required for a parent child type relationship. 
> Also it seems to me that it would be ideal to create an attribute with the guid of the parent / child and then derive the other one from the edge. I may have misunderstood but reverseAttributeName seems to use the name of the attribute not the guid.
> I suggest that iscomposite true and false is supported. 
> When we have this in place, we could use this mechanism for Glossary Categories
