One thing that struck me while reading this is that a longer, more
explicit description may benefit all users, not just those navigating
the page with a screenreader. Think, for instance, about users with
cognitive/learning disabilities. As Matthew already mentioned, title
would probably be the most appropriate. Two points worth mentioning, though:
a) in some cases, screenreader verbosity settings may determine whether
or not an element's title is announced - so you can't guarantee that users
will hear it in all circumstances;
b) (in relation to my "it's useful to everybody, not just screenreader
users" bit above) as far as I'm aware, there is no mechanism for users
employing keyboard navigation to present the title of the element which
currently has focus (i.e. the link they may have just tabbed to), so again
you cannot guarantee that all users will benefit from it.
Not saying it's not appropriate to use title, just thought it would be
good to mention these points for completeness' sake.
