Hi, A number of SVGs are in the W3C shadow dom spec <http://www.w3.org/TR/shadow-dom/>, so if there are improvements we can make to them, that would probably be *really* helpful. They are basically all tree diagrams, although some have extra links that make them directed graphs rather than true trees. So figuring this out is probably going to be helpful. I had a go at cleaning up the simplest example I found: <http://w3c.github.io/webcomponents/publish/shadow/WD-shadow-dom-20151008/composed-tree.svg> and made a version at <http://svg-access-w3cg.github.io/use-case-examples/composed-tree.html> that is an improvement. On Mac it is possible to navigate all the nodes with Yandex browser and VoiceOver, and after I made the labels much more explicitly redundant it sort of with works Firefox plus VoiceOver, but Safari crashes the page and reloads it. On Windows apparently the labeling apparently still doesn't work properly. The navigation is broken all round. If aria-flowto worked we could fix that, but apparently it doesn't actually work anywhere as designed.
