My claim, however, is that given that any software interface can be modeled using a "data model" as implemented in a programming language, it is not possible to use the RM as the sole data model for the software interface to a user. There is no collection of statements that can be executed in a language that implements the RM (solely) that can yield the data view for an arbitary UI.

I'm not getting this through however, so either a) My definitions and logical steps are not tight enough to make this clear to most readers (I suspect that is the case) or b) I'm wrong (always possible, but I think I have a real point on this one that I'm just not getting through adequately).
