Re: disposition of ISSUE 30 cited in bug 10967 insufficient

aloha, sam!

i do NOT want to open a new bug -- there are already several 
related bugs but none of them really addresses the issue:
the failure of the HTML WG chairs to provide an alternate or
improved mechanism for providing a long description -- i have
drafted requirements for verbose descriptors which i have not
only logged as a bug, but which i have submitted to the PFWG
and the HTML A11y TF as a set of requirements which MUST be 
fulfilled in order that ISSUE 30 is adequately addressed --
simply stating that longdesc is obsolete is NOT a solution

an attempt to bridge this gap has been presented to the WG as 
both a bug:

http://www.w3.org/Bugs/Public/show_bug.cgi?id=10853

as i indicated, though, this is a placeholder bug intended to fill 
the hole in HTML5 left by the chairs' decision on ISSUE 30 -- in 
particular, the chairs' failure to identify an equal or enhanced 
mechanism for providing a verbose descriptor -- a full exploration 
of the issue and its potential solutions, plus use cases, research 
etc. (performed by both laura and myself) can be found at:

http://www.w3.org/WAI/PF/HTML/wiki/Verbose_desc_reqs

it is this document which seeks to redress the gaping hole in HTML
that the chairs' decision on ISSUE 30 failed to address -- if not
LONGDESC, then what?  the functionality is needed; research has been
performed and URIs collected; LONGDESC will continue to be supported
by HTML4-compatible browsers, but it either needs to be re-engineered
so that it can reference internal as well as external descriptions OR
it needs to be restored for external descriptions and a new attribute,
a native @describedby, needs to be added to provide internal descriptions
through the use of IDREFs (a space separated list of IDs which can be
concatenated by an assistive technology into a cohesive long description
as well as providing a means for applying style to the long description
to visually bind it to the image being described for those -- such as
those with some types of cognitive disabilities or those with an 
extremely limited viewport -- who NEED a verbose description to guide
them through the image

what i AM asking for is an end to the chairs stating that issue 30
has been resolved no matter how many times the chairs repeat that it
is resolved -- as long as there is no replacement or enhancement for 
the LONGDESC mechanism, ISSUE 30 has NOT been resolved

or, is it the chairs' position that HTML5 does not need a verbose
description mechanism?  that is the message i keep hearing when 
i hear that ISSUE 30 has been closed by the chairs, full stop

LONGDESC was SPECIFICALLY added to HTML4 to increase the web's 
accessibility -- it was irresponsible of the chairs to remove 
longdesc WITHOUT providing a means or at least pointing the way 
forward to an enhanced verbose descriptor mechanism, as several 
members of the HTML WG have done -- ISSUE 30's resolution SHOULD
have been that LONGDESC's removal is conditional and should only 
be removed IF a superior or equivalent mechanism is agreed upon...

an attempt to resolve the lack of a verbose descriptor mechanism in 
HTML5 in an attribute agnostic manner of is what is located at:

http://www.w3.org/WAI/PF/HTML/wiki/Verbose_desc_reqs

and which was filed as bug 10853

http://www.w3.org/Bugs/Public/show_bug.cgi?id=10853

in closing, i would like to point out that i am not the only member
of the HTML A11y TF or the HTML WG who has pointed out the fallicy
of considering ISSUE 30 closed simply through the removal of LONGDESC, 
without the chairs stating that a verbose description mechanism is 
needed...  moreover, attempts to resolve the hole left in HTML5 by the 
chairs decision in ISSUE 30 have been given extremely short shrift by the 
chairs, who constantly fall back on their decision in ISSUE 30 without 
actually addressing the underlying issue: how to natively provide verbose 
descriptions for images by reference to structured content in an 
external document AND by reference to structured content that appears
in the same document as the image, with the understanding that the 
description may be comprised of several spans of structured text that
are not contiguous in the document (hence the need for internal 
references by a white-space separated list of IDs)

therefore, i would ask the chairs to re-examine ISSUE 30 in light
of the information contained in:

http://www.w3.org/WAI/PF/HTML/wiki/Verbose_desc_reqs

and

http://www.w3.org/Bugs/Public/show_bug.cgi?id=10853

because deprecating LONGDESC without providing the means for a verbose
as necessary description mechanism which does not force a visual 
encumbrance on the document, but which can be exposed simultaneously
with the image it describes, solves nothing...
