Application Domain - Separate Definitions

When loading an SWF into a SWF:

Is it possible to specifiy which class definitions will be added and which will be placed in a child of the system domain?

Previously, I was loading a SWF into a child of the current domain. Everything was working fine until I added a reference to one of the classes in the current domain. (I’m not instantiating the class until the SWF is loaded). Now the class looks in the current domain for classes exported by the SWF.

My problem is solved by loading the SWF into a child domain of the system domain. However, I have some classes that need to be the same in all children of the system domain.

I’m not completely sure this is the best approach. Any recommendations would be great!
