Hi, Sasha and experts, Regarding to the presentation of the contribution D.162 at the Q.2 meeting today, I searched too quickly to the ASN.1 structure. Instead, the issues that I found to adding the proposed GenericInformation field to UserInputIndication and EndSessionCommand messages should not have "SEQUENCE OF". Reasons are: - as GenericInformation is equivalent to GenericMessage or similar to GenericCapability, indeed no other CHOICE structure using it has "SEQUENCE OF" - The use of GenericInformation in UserInputIndication and EndSessionCommand messages are also expected to be declared in TerminalCapabilitySet. Since each GenericInformation message has its own messageIdentifier, if "SEQUENCE OF" exists, the same message can have more than one modes simultaneously, causing confusion and potentially interoperability problem. If more than one modes are expected, a nested GenericParameter could be specified. Therefore, I think it is not suitable to use "SEQUENCE OF" for the proposed GenericInformation in UserInputIndication and EndSessionCommand messages. Please let me know if you have the same view.
