Description Leif Halvard Silli 2010-06-25 22:34:47 UTC
How does longdesc and @aria-describedby work together?

What should happen when/if both are used on the same <img>? Solving this problem will tell authors whether it is useful to use both, or always just a waste of time/space,  sometimes useful etc.

Example:

<img 
   aria-describedby=samepage-fragment  
  longdesc=#samepage-fragment 
  src=foo alt="Foo. Bar.">

What if aria-describedby contains a IDREF _list_? Should that impact how one uses @longdesc? 

Example:

<img 
   aria-describedby=samepage-fragment-1  samepage-fragment-2 samepage-fragment-3
  longdesc=#samepage-fragment-1
  src=foo alt="Foo. Bar.">

Are there cases when it is useful to _both_ point to long description on the same page (via aria-describedby) _and_ to a long description on another page? Or should this cause a warning, for some reason?

Example:

<img 
   aria-describedby=samepage-fragment  
  longdesc=other-page 
  src=foo alt="Foo. Bar.">

The bug triage sub-team thinks the HTML A11Y TF does not need to formally follow this bug. Original submitters or other interested parties may choose to continue to push this issue on their own. Notes from the sub-team may follow in a separate comment.
Comment 5 Michael Cooper 2010-08-31 13:43:45 UTC
Bug triage sub-team notes that this issue is captured in the text alternatives proposal http://www.w3.org/html/wg/wiki/ChangeProposals/ImgElement20090126 and it is already defined that ARIA overrides native features.
