Steve Lawrence commented on DAFFODIL-2488:
------------------------------------------
I suggest the right thing to do here is to output "unparser: not available" or
something along those lines. This is similar to how if there is not an infoset
yet and you try to run "info infoset" you'll get "no infoset".
> When executing a parse command with the debugger get incorrect result for
> display info unparser
