Child attributes of RDO and ListRDO classes are handled a bit differently: In Rational Rose, RDO and ListRDO classes used to have two stereotypes of attributes: <<dataitem>> and <<description>>. The description stereotype was used to identify which attribute should be used as the description for that RDO/ListRDO.
In Rational Software Architect, the description stereotype is no longer used for these attributes; instead the dataitem stereotype has a booleandescription property to indicate that it is the description for the RDO/ListRDO. As with thedescription stereotype in Rational Rose, only one child attribute of the RDO/ListRDO should have itsdescription indicator set to true.
