What accessibility features, exactly? For compatibility, the deepest
child of <object> would be <img alt>, inheriting the accessibility
features of img. Alternatively, it might just as well be markup, which
is surely better accessibility wise than @alt and @longdesc.
Furthermore, you could theoretically link to an animation, a still and
a sound and embed a hypertext fallback.
(I'm sorry if <object>'s being generally terrible for accessibility
has been established already.)
