NOTE 1:
If the UE is provisioned or pre-configured with URSP rules by the HPLMN or serving SNPN, the UE handles the precedence between EDN connection info and URSP rules as defined in clause 6.1.2.2.1 of TS 23.503. EDN connection info is considered to be part of UE Local Configurations.
NOTE 2:
EAS information is limited to the EEC requested applications. If no AC profiles were present in the service provisioning request, the EAS information is subject to the ECSP policy (e.g. no EAS information or a subset of EAS information related to the EES).

At least one of the IEs shall be present if EAS bundle information is provided.
NOTE 4:
"Instantiation criteria" IE shall be present only when the value of "Instantiable EAS information" IE is "instantiable but not be instantiated yet".
NOTE 5:
"Application Group ID list" IE shall be present when "Application Group profile" is included for "AC profile" in service provisioning request as specified in clause 8.3.3.3.2.
