hi Bruce,
I see what you say but i would like to let you know that This
cross-referencing actually helps in extending the PFC. Let me explain...
If you did not like the sort service or found some bug in some of the
service which is being used by other PFC service. Now you could go and patch
it up or put in your extensions in the PFE layer. Since these PFE layers are
referenced or as you say cross-referenced, the patches you put or extensions
you make are available to other PFC services to use. This way you can
achieve global extension.
Thats another good reason why it is suggested to make extensions under a
insertion layer between PFC and PFE and not to descendents of PFE.
Thus due to Cross-reference changes made at extension layer are made
available at PFC layer.
You could have a peek at a very good book by William Green. "The PFC
Reference."

Ok, for the people who have replied to this.
I am not suggesting no pfe layer. I do actually use it and like the
functionality it provides. What I do take issue with is the
cross-inheritence between layers - the base windows are a perfect
example. That is what my meaning was in the first place, don't think I
explained myself very well.
Regards
