Add a new IE in the RRC message.
Could some ASN1 experts confirm , if i want to add a new IE, under, RRCReconfiguration-IEs, which is the correct way to add ?

RRCReconfiguration ::= SEQUENCE {
rrc-TransactionIdentifier RRC-TransactionIdentifier,
criticalExtensions CHOICE {
rrcReconfiguration RRCReconfiguration-IEs,
criticalExtensionsFuture SEQUENCE {}
}
}

RRCReconfiguration-IEs ::= SEQUENCE {
radioBearerConfig RadioBearerConfig OPTIONAL, -- Need M
secondaryCellGroup OCTET STRING (CONTAINING CellGroupConfig) OPTIONAL, -- Need M
measConfig MeasConfig OPTIONAL, -- Need M
lateNonCriticalExtension OCTET STRING OPTIONAL,
nonCriticalExtension RRCReconfiguration-v1530-IEs OPTIONAL
}

RRCReconfiguration-v1530-IEs ::= SEQUENCE {
masterCellGroup OCTET STRING (CONTAINING CellGroupConfig) OPTIONAL, -- Need M
fullConfig ENUMERATED {true} OPTIONAL, -- Cond FullConfig
dedicatedNAS-MessageList SEQUENCE (SIZE(1..maxDRB)) OF DedicatedNAS-Message OPTIONAL, -- Cond nonHO
masterKeyUpdate MasterKeyUpdate OPTIONAL, -- Cond MasterKeyChange
dedicatedSIB1-Delivery OCTET STRING (CONTAINING SIB1) OPTIONAL, -- Need N
dedicatedSystemInformationDelivery OCTET STRING (CONTAINING SystemInformation) OPTIONAL, -- Need N
otherConfig OtherConfig OPTIONAL, -- Need N
nonCriticalExtension SEQUENCE {}
}

Is the following insertion correct ?

RRCReconfiguration-IEs ::= SEQUENCE {
radioBearerConfig RadioBearerConfig OPTIONAL, -- Need M
secondaryCellGroup OCTET STRING (CONTAINING CellGroupConfig) OPTIONAL, -- Need M
measConfig MeasConfig OPTIONAL, -- Need M
newIE newIEType OPTIONAL,
lateNonCriticalExtension OCTET STRING OPTIONAL,
nonCriticalExtension RRCReconfiguration-v1530-IEs OPTIONAL
}
