Can one access asn1ct's ASN.1 parser?

We have discussed to add functionality in the generated encoder (for the
maps variant) which checks that the map does not contain any "unknown"
keys, that is only allow keys which are corresponding to the names in the
ASN.1 spec. Probably this should be activated with a new compiler option
since it will probably have some negative impact on performance.

Is this what you need as well or are you thinking of some other solution
(or other problem)?

There is no API for the parse tree but there is an internal intermediate
format used by the backends.
