You should obtain the CDR ASN.1 module file, compile it with asn1c, and then use the resulting binary to decode this.

unber just shows the structure, without any interpretation.

Are all the Length closing values of your ASN1 data expressed in an XML format.

ASN1 is essentially a TLV (Tag Length Value) - a DESCRIPTOR (If you are from a VMS background).

As to what structure/values they are - you will need your ASN1 spec to work that out.
