Technical Report: Unresolved Challenges and Potential Features in EATXT

We developed a textual concrete syntax and a textual editor that supports it for the domain-specific language EAST-ADL, which we named EATXT. This document is a technical report that describes potential advanced features that could be added to EATXT that have not yet been implemented. The purpose of this report is to share our understanding of the relevant technical challenges and to assist potentially interested peers.
