asn1 improvement proposal
Tue Aug 26 11:14:15 CEST 2003
We have been thinking on a solution like that earlier but didn't find
time and motivation to implement it then.
It would be ok to receive the unknown "elipsis" parts as an undecoded
binary and to pass that to the encoder function for further
distribution, but I think is would be difficult for the user to create a
correct binary on his own and pass to the encoder.
I think your suggestion is worth taking up and we might implement it in
a coming version although we have to think about compatibility too.
