Sure. It simplifies the architecture of AE + Mediator by only having one 
entity now. What I mean is that before, part of the job was done by the AE in 
the DSS, and the other part by the Mediator in the Glue. Now, the AE does not 
exist in the DSS any more (it's only an interface), therefore, more work is 
done at the Glue layer.
