The Property Tab
The element Properties dialog for Ports and Parts has a Property tab in place of the Class element Details tab. This tab defines the type, initial value, Qualifiers, multiplicity, and redefined and subsetted properties of the Port or Part.
You set the Qualifiers by clicking on the Qualifiers button, to display the Qualifiers dialog. You add Redefined and Subsetted Properties by clicking on the appropriate Add button, to display the Select Property dialog.
