The reason for creating the abstract base classes and placing them in an RSL is so the modules (seperate swfs) can be developed and compiled with strict data typing to particular value objects and models that are retrieved from the ModelLocator which exists in the main shell application.
The modules are basically completely independent swf files (built from standalone flex projects) that the main shell application will only load as the user requests them (ie click on a button to open a particular tool, and that tool's swf will get loaded and displayed in the main shell application).
