the Q.2 meeting today, I searched too quickly to the ASN.1
structure.   Instead, the issues that I found to adding the proposed

should not have “SEQUENCE OF”.  Reasons are:<o:p></o:p></span></font></p>

style='font-size:10.0pt;font-family:Arial'>as GenericInformation is equivalent

style='font-size:10.0pt;font-family:Arial'>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.<o:p></o:p></span></font></p>
