We do the latter: relative to @ref (or @bind: that is relative to the
binding when present).

Another way to look at it is that attributes which evaluate XPath
expressions work like expressions on nested elements (except @origin as you
pointed out).

How about with:
>         <itemset model="flavors" ref="flavor" label="{description}"
> copy="description"/>

So same here, `description` is relative to `flavor`.

select/itemset/@copy: Element or in-scope?

"element"

There is no @ref/@bind on `setindex`, but there could be a @model or
@context. So relative to that.

I would say that too.

Yes.
