LQ::  The D-link is a constant reminder to the non-visual user that she is
viewing a visual page.  A page that provides seamless accessibility makes
the non-visual user (and every other user) feel that the page is made
specifically for her, specifically for her browsing environment.  If you
were writing a page specifically for a non-visual browsing environment, you
would not include an image, so the seamlessly accessible page should appear
to be imageless when viewed by a non-visual user.

LQ::  Yes.

LQ::  An author would use the LONGDESC attribute of IMG rather than an
explicit D-link.  With OBJECTs, the author has no method to give a long
description since there is no LONGDESC attribute on OBJECT; perhaps a
future version of HTML will fix this.

User agents should, by default, hide long descriptions unless requested to
show them (either all the time or for the current page).  In Lynx, the "*"
command key should add a "[D]" or "[Desc.]" link right after the "[IMAGE]"
(which could probably be replaced by the IMG's TITLE in brackets).  A
graphical browser could do something similar, with the IMG's TITLE linked
to the long description and displayed in brackets (or perhaps an inset
frame) just after the ALT text.
