Hi Jonas,

> Also, please don't argue to *me* that removing support is bad.

I wasn't arguing that. I was stating a fact about Opera's support.

Also a fact: WAI CG Consensus Resolutions on Text alternatives in HTML 5 stated:

 Because we are confident that aria-describedby will be supported by
assistive technologies at least as well as longdesc when HTML5 becomes
a W3C Recommendation:

* IF
   - aria-describedby is incorporated in HTML5
   - and aria-describedby allows pointing to long text alternatives
that are off of the page (by pointing to a link on the page)
   - we believe it is acceptable to obsolete longdesc in HTML5.

RATIONALE: It is important that a long text mechanism exist which is
capable of pointing off page. Long descriptions are often too lengthy
and detailed to be included on the main page. If aria-describedby can
point off page (by pointing to a link on the page) then it would
remove any need for continued support of LONGDESC which is not widely
used by authors at this time. (NOTE: it is understood that
aria-describedby cannot point off page directly.)"
