PowerDesigner provides default model checks to verify the validity of group articles.

Check	Description and Correction
Existence of particle	A group particle must contain elements, groups, group particles and/or Any. Manual correction: Add items to the group particle or delete it Automatic correction: None
Invalid cardinality	You should define a minimum (0 or 1) and a maximum cardinality (1 or unbounded) for a group particle occurrence. This check is only available in a model targeted with XDR. Manual correction: Double-click the group particle symbol and type a value for Minimum (0 or 1) and Maximum (1 or unbounded) properties Automatic correction: None
