The following tables lists unsupported features of the DFDL Specification since Daffodil v1.0.0, and planned implementation roadmap.

The releases are identified by the theme of the release - the primary things the release is supposed to achieve.

 

  (tick) = supported     (error) = unsupported     (warning) = partially supported (mouse over the symbol to display reason for partial support)
