> 3.4.0-SNAPSHOT - as of 2022-08-23.
> I have unparsing in a large complex DFDL schema failing with a Index out of bounds - an empty stack of infoset nodes. 
> I think this is going to be a blocker for the release as I think there is no workaround, but further work may change this. 
> By inspection it looks to be a bug where the index value isn't being checked, as the function can return Nope or One(value), but instead throws the exception.
> Working on a way to reproduce this outside of this very large schema project.
