 From there, the walker evolved from SRE-specific markup to a general purpose aria(-owns) tree walker. At that point, it was forked to this repository and continued as aria-tree-walker. The goal is to support any such tree (e.g., complex diagrammatic content) and to gradually improve the user experience.
