Access Key

Editing the XHTML 2 spec, I came across something I wasn't sure of.

If an access key is on a link, should the access key take you to the link,
where you must then activate the link (with return or space or whatever), or
should it immediately follow the link.

HTML 4 says follow the link, but I note that UAs aren't consistent here. My
personal feeling is that the link should get focus, so that you can then
decide what to do with it, but I'd like to hear from WAI people.

Thanks!
