You probaly want:

#.FN_HDR TargetRNC-ToSourceRNC-Container/dL-DCCHmessage

  {   1, &hf_rrc_radioBearerReconfiguration, ASN1_NO_EXTENSIONS     , dissect_rrc_RadioBearerReconfiguration },
  {   2, &hf_rrc_radioBearerRelease, ASN1_NO_EXTENSIONS     , dissect_rrc_RadioBearerRelease },
  {   3, &hf_rrc_transportChannelReconfiguration, ASN1_NO_EXTENSIONS     , dissect_rrc_TransportChannelReconfiguration },
  {   4, &hf_rrc_physicalChannelReconfiguration, ASN1_NO_EXTENSIONS     , dissect_rrc_PhysicalChannelReconfiguration },
  {   5, &hf_rrc_rrc_FailureInfo , ASN1_NO_EXTENSIONS     , dissect_rrc_RRC_FailureInfo },
  {   6, &hf_rrc_dL_DCCHmessage  , ASN1_NO_EXTENSIONS     , dissect_rrc_OCTET_STRING },

Hi,
 
which OCTET STRING type do you need to modify?
It is not possibe to modify "common OCTET STRING".
 
You can use #.FN_HDR/BODY/FTR e.g. in following way:
 
NAS-Message ::=      OCTET STRING (SIZE (1..4095))
#.FN_HDR NAS-Message
...
 
or e.g.
 
RAB-Info-v6b0ext ::=    SEQUENCE {
 mbms-ServiceIdentity    OCTET STRING (SIZE (3))
}
 
#.FN_HDR RAB-Info-v6b0ext/mbms-ServiceIdentity
...
 
Regards,
Tomas
