Jim,
As CER is a subset of BER I cannot see how the cost of adding support
for CER can be so significant.
I must ask a different question. DER was defined in 1988 and many folks
have implementations, and the specification must continue to support DER
for backward compatibility. Given these facts, what is the value of CER
over DER that makes it worth the additional development and testing? I
understand the desire for single pass processing, but I am not convinced
that the improvement in single pass processing is worth the hastles to
support two encoding formats.
