recommendation for bug #1741 SC 2.4.2

 

I had taken an action item to address bug #1741present my recommendations to
Team B. The bug is here:

 

http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1741

 

and to suggest possible rewording of the SC, or other solution if necessary.

 

The SC is here:

 

http://www.w3.org/WAI/GL/WCAG20/WD-UNDERSTANDING-WCAG20-20051216/Overview.ht
ml#navigation-mechanisms-mult-loc

 

The Bug shows that the SC as it is currently worded introduces confusion
about whether the author must provide more than one way to access each
delivery unit in a set, or provide more than one way to navigate to *all
content* which could also include each subsection of a delivery unit (i.e,
the 3rd sentence in paragraph 2 of section 1)

 

I think the intent of the GL is to provide more than one way to each
delivery unit, rather that providing more than one way to navigate to every
bit of content. 

 


Recommendation 1


 

<current>

2.4.2 More than one way is available to locate content within a set of
delivery units where content is not the result of, or a step in, a process
or task. </current>

</current>

 

<proposed>

2.4.2 More than one way is available to locate each delivery unit within a
set of delivery units where the content of the delivery unit is not the
result of, or a step in, a process or task. 

</proposed>

 

I think this would clean up the confusion. I would then close the bug and
get back to the person filing the bug saying that we have clarified the
language of the SC, and that we have overcome the possibility of the author
providing two inaccessible solutions in GL 2.1, 2.4.1

 

Bug 1741

 

Guideline 2.4 - Level 2 - 1: What if a single way is accessible for all?
Would 

be silly to require the addition of another method of locating content when 

there is only one paragraph in an authoring unit where each sentence is 

provided by a different delivery unit. Also creates the possibility of 

providing two different ways of locating content yet none are usable for 

visually impaired users. The requirement should be that one or more ways of 

locating content must be provided in order to ensure barriers in locating 

content is minimized. Very difficult to word but the way it is now seems
like 

a huge loophole to us. [TWG]
