>                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2628
>             Project: Daffodil
>          Issue Type: Bug
>          Components: Back End, Middle "End"
>    Affects Versions: 3.2.1
>            Reporter: Mike Beckerle
>            Assignee: Mike McGann
>            Priority: Major
>             Fix For: 3.5.0

> Debugging a schema I created this little thing to print out a length I wanted to see:
> ```
>         <dfdl:assert test='{ dfdlx:trace(dfdl:valueLength(message, "bytes"),"contentLen")  }'/>
>  
> ```
> Notice the mistake. I forgot to compare the value to 0 in the test. 
> That expression returns an integer.
> If you fix the expression (add " ge 0") then everything works fine.
> But with the mistake you get an abort at runtime:
> ```
> trace contentLen:DataValue(true)
