>             Project: Daffodil
>          Issue Type: Bug
>          Components: Back End
>    Affects Versions: 2.5.0
>            Reporter: Mike Beckerle
>            Priority: Major

> Currently, lengthKind 'delimited' accepts finding a delimiter or end-of-data as satisfying the need for a delimiter.
> This is not DFDL spec compliant. The DFDL spec allows for one case where a delimiter that is required (by lengthKind 'delimited') is not present, and that is by way of the property dfdl:documentFinalTerminatorCanBeMissing. This suggests no other exception to finding a required delimiter should be allowed. 
> Fixing this may require a compatibility mode tunable that can be set to obtain this prior behavior. However, tests in our test suite should not be made to work using this compatibility mode.
