Replying all for the benefit of the list.

There used to be a 'label' role in the draft, but it was removed a few years ago. The reason is because the user doesn't need a label role. They just need to hear the label text on the labeled element, no matter the role of the labeling element. For example, sometimes an element is labeled by a heading; sometimes by a simple span. To put it another way, the important semantic of the <label> tag in HTML is not its role, but the relationship provided by the @for and @id attributes.
