It's easy to make content and functionality available to an accessibility API
but still hard to use, people do that all the time.

Same way as content focus is normally tracked? I don't understand the problem

If you navigate a same-page link, then navigate back, keyboard focus should
land on the same-page link. (There may be client software where that doesn't
happen, however that's a clear usability defect.)

Users have the option to open the footnote link in a new window, which should
provide the same experience as an AT triggering opening @longdesc in a new

Authors have the option of linking to notes on other pages, or suggesting the
opening of a new window with @target=_blank.

Client software has the option of developing specific behaviors around
@rel=help such as always opening help links in a new window.
