3GPP TS 29.078 11.0.0 is for Camel phase 3.
For Camel phase 2 you must check GSM 09.78 version
7.1.0(http://www.3gpp.org/DynaReport/0978.htm) and in that document tag 7 is
for serviceInteractionIndicatorsTwo, see below

EstablishTemporaryConnectionArg     ::= SEQUENCE {
    assistingSSPIPRoutingAddress        [0] AssistingSSPIPRoutingAddress,
    correlationID                        [1] CorrelationID                     
  OPTIONAL,
    scfID                                [3] ScfID                             
  OPTIONAL,
    extensions                            [4] SEQUENCE SIZE(1..numOfExtensions)
   OF
                                                            ExtensionField     
   OPTIONAL,
    serviceInteractionIndicatorsTwo        [7] ServiceInteractionIndicatorsTwo 
      OPTIONAL,
      ...,
    na-info                            [50] NA-Info                           
OPTIONAL
    }
