To create a class in a schema, select the associated menu item in the Insert menu or the schema context menu. The new class will be created with automatically generated name and position. Note that classes of the same name in different schemas are considered different.

When a class is selected, the Data tab in the properties panel allows the user to change the class name, and to create/delete attributes. The Definition tab is activated to introduce a DLR expression that constraints this class.
