>Why do we need to model concepts?

Is this just the classic software engineering debate about the value of
closer-to-executable requirements specs?    Which comes down to whether we
capture and analyse requirements using a natural tool (conceptual modeling)
or a generic toolkit (UML) or with implementation tools (e.g. DTDs), which
probably makes the choice a function of the complexity and criticality.

Do we make a conceptual modeling language in which pizza concepts can be
expressed (cold, late, don't-let-boy-with-zits-deliver-pepperoni, etc) and
then transform it? Or do we use a generic toolkit which has generic tools?
Or do we try to shoehorn into the low-level implementation system?  Why not
have all these options available and well supported?
