The SDL Integrated Tool Environment (SITE) supports BER according to
X.209 (which is interoperable with X.690). Please have a look at

The syntactical embedding of ASN.1 does not follow Z.105. Instead,
X.208 is supported literally, following the 'external formalism'

The BER itself complies with the DER restrictions on the producer
side. The consumer can decode all variants. A few constructs are not
supported, like encodings of external types.

Hope this helps,
