When defining an embedded list property with a specific data type:
Changing pxObjClass at Runtime (A):
The pxObjClass of any page within the .Loans list can be modified at runtime. This provides flexibility to change the class of individual pages if needed.
Inheritance and Calculation (C):
Extending the data model, such as a car loan application extending MyCo-Data-Loan-Auto, does not impact aggregate functions like sum performed on properties (e.g., .Loans().Amount).
Class Consistency within the List (E):
All pages within the .Loans list must adhere to the same class type, ensuring consistency and correct behavior of operations on the list.
