- packed decimal/BCD - know this stuff? Add this feature to daffodil. It's essential for Daffodil to run a number of the DFDL schemas on the github DFDLSchemas site.
- zoned decimal - heard of this? Needed for ISO8583 format, which has a DFDL schema on github.
- binary calendar types - we postponed this, and... well it needs to get done.
