In Access Control Policies, attributes like Appointment date (A) and Number of dependents (B) can be used to define conditions for data access. These attributes can be part of case data or user profiles and serve as criteria for determining access levels. For example, an access control policy can restrict access to certain case information based on the appointment date or allow access to specific functionalities based on the number of dependents associated with a user profile.References: Pega Community documentation on Access Control Policies.
