1.2.3 Repair Missing Associations:

The user can specify whether or not the user agent should attempt to 
predict associations from author-specified presentation attributes (i.e. 
position and appearance). (Level AAA)

Intent of Success Criterion 1.2.3:
Sometimes the closeness of elements within the document object model is 
not the same as the visual rendering. This means logical connections are 
implied by visual associates as opposed to the explicit order in the 
document object model. These associations are not available to visually 
disabled users - putting these users at a disadvantage. Using rendered 
proximity may help to redress some of these disadvantages and enable 
implicit associations to be explicitly identified when the content 
cannot be seen. Indeed, this success criteria is linked to WCAG 2.0 SC 
1.3.1 and provides for the requirement that 'relationships conveyed 
through presentation can be programmatically determined'.

Examples of Success Criterion 1.2.3
Fred is a blogger and use's a screen reader to gain access to the online 
software which facilitates data entry. However, Fred has problems with 
this software because buttons which are next to each other on the page 
are not spoken by his screenreader together because they are far apart 
in the visual presentation. Luckily Fred's new browser helps him by 
allowing adjacent items in the visual rendering to be explicitly 
identified - making his interactions much easier.

presented in different ways (for example simpler layout) without losing 
information or structure.
