Since Howard avers that the community of domain experts has reviewed and 
approved these models as accurate knowledge, I assume that Matthew is 
suggesting some kind of "model quality" analysis.  If there is published 
agreement on best practices in modeling (by a large body of experts in 
that field), then a team can be trained to employ those in doing the 
model analyis.  But I'm not aware of any such published agreement, and 
the last thing the systems engineering models need is model analysis by 
a self-appointed team with a consistent but not clearly appropriate 
viewpoint.    (03)

Howard, Matthew and others will recall the damage done to well-developed 
domain models by a team of expert SQL database designers considered to 
be "information modeling" experts in a not-so-distantly related ISO 
activity.  I can envisage coercion of the models to OWL/DL by 
well-meaning model analysts who have a similar shortage of breadth in 
their vision.    (04)

So the question is:  Where do the model analysis guidelines come from? 
And how will the analysts work with the domain experts to understand the 
intent when they don't like the structure of the ontology?    (05)
