Following discussion with Martin this is the new proposal for the
Minimality section of the CRM introduction.
Although the scope of the CRM is very broad, the model itself is
constructed as economically as possible.
* CRM classes and properties are either primitive, or they are key
concepts in the practical scope.
* Complements of CRM classes are not declared because considering the
Open World Assumption, there are no properties for complements of a
class (see Terminology).
* A CRM class is declared when:
* It is required as the domain or range of a property not
appropriate to its superclass.
* It serves as a merging point of two CRM class branches (e.g. E25
Man-Made Feature). Instances of the resulting class are narrower in
scope than those declared through multiple instantiation of the two
* It is useful as a leaf class (i.e. at the end of a CRM branch) to
domain communities building CRM extensions or matching key domain
classes from other models to the CRM (e.g. E34 Inscription).
