ISSUE - 7:
An AC Member asked that we remove the priority 2 requirement for redundant
text links for client-side image maps which is found in Checkpoint 1.2 They
felt that client side image maps are handled by text browsers and assistive
technologies today.  They suggested that  1.2 should say to provide
redundant links for server-side maps, when server-side maps are required.
They also suggested we refer to Checkpoint 9.1 in checkpoint 1.2.

In examining this item, it was found that there are user agents for all
platforms that will process client side image maps.  Thus the second list of
links is not necessary to provide access.  In fact, it can be confusing on
these browsers since it lists all of the links twice.  However, it is still
a usability problem for those who prefer browsers that do not expose client
side links very well.
The proposal is therefore to set the priority to 3 for client side image
maps because of the interference problem and the fact that access is
available through multiple browsers (Lynx, Opera, Pwwebspeak, HomePage
Reader, etc.)  The priority would remain 1 for client side image maps.

Same as Original Wording except priority for client side is set to 3. (It
was 2.)

1.2 Provide redundant text links for each active region of an image map.
[Priority 1 - if server-side image maps are used], [Priority 3 - if
client-side image maps are used.]  Redundant text links for client-side
image maps are only required until user agents render text equivalents for
the map links.
