RE: 2.4.2 Issues

The problem with "perceivable unit" (as I understand it) is that authors
can't control what happens when a single delivery unit is rendered as
multiple perceivable units, so ther emight not be a way to satisfy the
SC if we used David's wording  .

I'm not completely certain that I understand "perceivable unit"
properly. The term comes from the Device Independence WG's Glossary.
Could someone check it and se if we can determine whether perceivable
unit is or isn't under authorial contrl? (We may also need to check with
someone from DI WG to be sure on this one.)

Thanks,
John

Subject: 2.4.2 Issues


1. Issue 1825:
http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1825

Recommendation: Close this issue saying that 2.4.7 haw been changed to
remove "page or other".

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

Recommendation: adopt David Macdonald's proposal, which clarifies that
the SC only applies at the delivery unit level.

<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>

<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>

More of the issue might be addressed if we used "perceivable unit"
instead of "delivery unit". Would there be problems if we change this
to:

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