> Currently, the DMN Editor will default to a blank LiteralExpression on Save if the user did not provide an expression for an element.
> However Error message is reported anyway to the user:
>  !image-2019-11-04-19-39-01-113.png|thumbnail! 
> This also as the (imho undesired) side-effect that if the user was to re-open later that file, instead of a empty element, it would be a blank LiteralExpression
>  !image-2019-11-04-19-40-27-201.png|thumbnail! 
> so the current behavior is not consistent across re-open of the editor.
> Let's revert this default.
> The DMN Editor on save should +not+ default to a blank LiteralExpression if the user did not provide an expression for the element.
> Once this change is applied from the f/e side, I am happy to be involved in order to assess which of the messages reported by the Validator or the Compiler are causing issue to the WB (if any).
> Currently, the DMN Compiler will throw 1 Warning.
> Currently, the DMN Validator will throw 1 Error (I can align this to be a Warn too).
> Currently, the DMN Validator schema check is not reporting any XSD violation.
