Hi Jerry, 

...or we identify use cases we want to handle (and thereby take a
conscious decision to "de-scope" other use cases), and ensure that our
model is fit for (our) purpose. Then map the "official" data model onto
the "internal" model. This mapping will probably be a one-way mapping,
i.e. it is unlikely to be possible to go from the (simplified) OSM model
back to the standard model in a reliable way. 

I found this paper (2003) which shows some more of the vagaries of the
system. There is a short section on BS7666. It's a few years old now so
things have moved on a bit, but I reckon a significant part still holds
