> It is unclear how to create a parse/unparse error using ParseOrUnparseState while creating a layer transform. Currently we can create a SDE using ParseOrUnparseState, but there are situations where the issue is with the data, not the schema. 
> A possible workaround is to manually recreate what PE and UE do as in:
> {code:scala}
> parserOrUnparseState match {
>   case pstate: PState => // do what PE(...) does
>   case ustate: UState => // do what UE(...) does
> }
> {code}
> Related to DAFFODIL-2841
