ASN.1 doesn't specify encoding, just the "abstract syntax". There are multiple
encoding rules that specify the encoding.
asn2wrs only handles BER and PER, so it can't handle protocols not using them -
which also includes protocols not specified by ASN.1 at all - but if asn2wrs
were to handle the Encoding Control Notation:
https://en.wikipedia.org/wiki/Encoding_Control_Notation
it might be able to handle any protocol whose abstract syntax could be
specified by ASN.1 and whose encoding could be specified by ECN.
