This is the hash key of the attributes which make up the composite key--- CartOwner, CartId and AgencyId ---for the Payment Carts resource and used to uniquely identify an instance of Payment Carts. The client should not generate the hash key value. Instead, the client should query on the Payment Carts collection resource with a filter on the primary key values in order to navigate to a specific instance of Payment Carts.
For example: publicSectorPaymentCarts?q=CartOwner=<value1>;CartId=<value2>;AgencyId=<value3>
