>             Project: Daffodil
>          Issue Type: Bug
>          Components: Back End, Middle "End"
>    Affects Versions: 3.2.1
>            Reporter: Mike Beckerle
>            Priority: Major
>
> I get a runtime SDE when I have a situation like this:
> ```
> <element name="message" .....
>       .... big definition....
> </element>
> ....
> <dfdl:setVariable ref="$x:myVar">{ dfdl:valueLength(message, "bytes") }</dfdl:setVariable>
> ```
> The runtime SDE (when parsing) is that message has no value length. 
> (Working on test case to reproduce it.)
