Yes, or rather from 3gpp.org.

I'd like to have it added to asn/nbap/.
The file was edited by hand :-(
A possible solution could be to make a diff files between the
incompatible versions to find the incompatable
Asn1 parts then insert that asn1 code with a different name
Like:
Foo_v1::= foo_v1
Then insert a preference: Decode NBAP as V1,V2 etc
And do the necessary changes in the .cnf and ..-template.c to call the
different functions depending on the version.
Do you have an example of some differences and a trace file to
illustrate it with?
