aloha!

first, let me tender my retrospective regrets for missing this 
morning's XHTML2 working group meeting -- i have a 2 week old 
migraine i can't shake, and it was some of its ancillary side 
affects that kept me from attending the call, which a great 
disappointment to me, as there is much to be done and much to 
be discussed, especially in the realm of ARIA integration and 
recent developments on that front...

in answer to RichS' inquiry on behalf of the WG, the genesis of the 
post archived at:

http://lists.w3.org/Archives/Public/public-xhtml2/2007Jul/0012

was quite simple -- after discussing terse and long descriptions and how 
ARIA markup could be used to create bindings, i was asked by the XHTML2 
WG (in particular, StevenP) to provide an example of ARIA markup used to 
describe and contextualize a static image, as i had suggested to the ARIA 
editors before i discovered that the ARIA spec itself would not contain 
any ARIA markup for validation purposes...

it was a purposefully simple illustration so as to illustrate the 
bindings possible with ARIA that could be used to provide a long 
description of an image using content embedded in the document itself as 
descriptor text, while simultaneously stressing the connection between 
the description and the illustration not only programmatically, but 
visually, as well, for those who can see, but who prefer to examine 
detailed objects as a self-contained whole, hence the wrapping of the 
image and the caption text in a visual box, so as to indicate to those 
not using ARIA markup such as those with cognative processing issues 
(which won't be addressed until version 2.0) at least have a concrete 
binding alerting them that this image is related directly to this 
text...

the example was originally sparked by our conversation late last year or 
earlier this year about provision of LONGDESCs for the illustrations and 
diagrams in the ARIA documents, as you were loathe to use actual 
LONGDESC pages, due to the extra effort involved in maintaining them 
as the draft is updated...

i made a careless CSS error in my original post, which i had to correct
with the follow-up post archived at:

http://lists.w3.org/Archives/Public/public-xhtml2/2007Jul/0013.html

the always astute gez lemon followed up my post with an alternate 
suggested means of using ARIA to provide bindings between the image
and its textual "equivalent" or "expansion"

i hope this clarifies the example's purpose and content -- if not, 
please let me know and i will attempt to be clearer,

gregory.
