This will be used by the reorderer to announce the location of a given reorderable element, as well as to announce its new location on reordering. This little component will be akin to the way we are able to add tabindex to an element.
Several variations of this component will be needed:
1. A static label component that makes it easy to associated elements with labels using aria-labelledby
2. A dynamically changing label, which is updated based on user interactions. This may be implemented by switching the element's aria-labelledby on the fly, or may need to be implemented using a live region
