>             Project: Daffodil
>          Issue Type: New Feature
>          Components: Back End, DFDL Language
>    Affects Versions: 4.2.0
>            Reporter: Olabusayo Kilo
>            Priority: Major

> The DFDL spec (12.3.6) explicitly mentions that an EndOfParent element
>  can be terminated by a choice with choiceLengthKind='explicit', with no reference
>  to implicit length choices. Later on in 12.3.6, it specified what the parent Effective 
>  Length Units would be for an explicit length choice, again with no reference to 
>  implicit length choices. The only way to get an EndOfParent element within an
>  implicit length choice would be to have it actually be terminated by the choice's
>  parent, similar to how we treat elements within an element that is also EndOfParent.
> Alternatively we can also add a choiceLengthKind="EndOfParent" that looks to the parent's parent for the effective length unit of the parent.
