The JTC are working on a number of other Rules, which are all
derived from BER to improve the performance of the transfer syntax.
They are described in the Addenda/Amendments to IS8825/CCITT X.209.

The new sets are:

DER (Distinguished ER) which basically imposes transfer orderings on some
classes of fields

PER (Packed ER) which 'squeezes' down the BER patterns

LWER (light Weight ER) which is designed for faster processing, by requiring,
for example, that all strings start on word boundaries.
