(BER) ASN.1 encoding rules for
producing self-identifying and self-delimiting transfer
syntax for data structures described in ASN.1 notations.
BER is an self-identifying and self-delimiting encoding
scheme, which means that each data value can be identified,
extracted and decoded individually.
Huw Rogers once described BER as "a triumph of bloated theory
over clean implementation". He also criticises it as designed
around bitstreams with arbitrary boundaries between data which
can only be determined at a high level.
