There are several well-known problem areas in the UML (Version 1.3). Although many of these have been reported to the OMG's Revisionary Task Force (RTF), that venue is highly pragmatic; here we consider the detailed “theory” relating to these problem areas. We first discuss the widely used concept of stereotypes and then concentrate on the metamodel for (i) WP relationships, (ii) Responsibilities; and (iii) Type/Interface/Class. In addition, we identify areas of the metamodel where the UML has been used inexpertly, particularly in the incorporation of generalization to incorrectly represent implementation inheritance relationships and the use of black diamond composition for relationships that are poorly argued to be whole-part relationships. Other issues discussed here include the default directionality of associations; the relationship of an association to a dependency; and the general observation that the UML uses a notation that supports expressibility but is not in itself expressive.
