1. MAJOR: 1.1 Support for PER encoding. Requires advanced subtype constraints support, which is already completed. Also see #3.2. 1.2 Support for Information Object Classes. Status: Support for parsing IOCs is mostly present. Support for slicing the IOCs to produce "views" is not yet designed. 2. MEDIUM: 2.1 Support for DEFAULT encoding and decoding, at least in INTEGER/ENUMERATED types. 2.2 Support for EXTERNAL, EMBEDDED-PDV and CHARACTER STRING types. 3. MINOR: 3.1 Parsing of CONSTRAINED BY clauses 3.2 Support for ContainedSubtype constraint. 3.3 If the generated target language source file is not different from the one already present (except maybe a compiler version in comments), do not update the file. Prevents trashing file dependencies in multifile compilation.
