DER is a strict subset (i.e. profile, i.e. specialisation) of BER.
Which means that whatever can decode BER can also decode DER.
So the answer to question a) above is YES for ANY decoder (not only SNACC)
For questions b) and c) a SNACC expert is needed to give a definite answer.
All SNACC-encoded objects I've seen were DER-compliant, but this is not
so much; only the SNACC specs (or doc, maybe even code) can tell it
for sure.
