Core Data questions re: primary keys and modeling tool

I'm starting to work with Core Data and have a few questions about the data modeling tool capabilities / limitations:

1) Is it possible to define a primary key for an entity in the model and if so, how? How about composite keys? If this is not supported, any suggestions or best practices on how to implement equivalent functionality? 2) How is the modeling tool determining which attribute to base a lookup on for in automatically created by option-dragging to windows and is it possible to change this attribute in the model or does it need to be changed in IB after populating the form? 3) How is the modeling tool determining object (attribute etc.) order and is it possible to change the order? _______________________________________________ Do not post admin requests to the list.
