$elementStatus variable is unused

[nerdoc]

found this while translating into python:

https://github.com/search?q=repo%3Aphp-edifact%2Funtdid-parser%20elementStatus&type=code

All these variables seem to be left from a refactoring?
They are only written, never read. It should be safe to delete these lines.

I think it held the change marks on elements (X to mark for deletion and so on) but I didn't output them
