* Describes the bean provider's view of a relationship. It consists of an optional description, and the name and the class type of a field in the source of a role of a relationship. The CMRField::name element corresponds to the name used for the get and set accessor methods for the relationship. The CMRField::type element is used only for collection-valued CMRFields. It specifies the type of the collection that is used (a java class name).
