If the browsers provide a way to visually display the description - e.g. in an overlay - then the authors can check the result of their work for themselves. I would also suggest that a link to an element would just display the page fragment rooted at that element. If an author wants to include more than that, then they would put a div or p or so around the set of elements that they want to link to and reference that. It won't break HTML or fragment URIs. It's just a semantic of this attribute. Silvia.
