Given that SVG can be integrated directly into HTML, it makes more sense to work in parallel with them.

I note that they already had a concept of focus navigation that was probably more like what we are looking for than the current tabindex.

A use case is to build a component that is used in various pages, in different locations, and locally assign tabindex within it, but not have that tabindex override the order of tabbing around the rest of the page.

So the requirement *might* be something like being able to scope a set of tabindex attributes, such that they only apply within the scope.
