8 Source and Harmonization of Recommendations

8.1   Source of Recommendations from the Current 8 and 255
8.2   Harmonization of the Recommendations to WCAG 2.0
8.3   Identification of Provisions Supporting Functional Performance Criteria

8.1 Source of Recommendations from the Current 508 and 255

The reorganization of the provisions has made it possible to consolidate a number of the technical requirements from current Section 508 into a single provision in the recommendations. An example is 3-A:  Color, which consolidates 1194.21 (i), 1194.22(c) and 1194.25(h).

Provisions from the current Section 508 which have been consolidated, or dropped are:

1194.22 – Web-based intranet and internet information and applications

(d) Readable without a style sheet
Style sheets are well-supported. What is needed instead is a provision on reading order, which is provided in 3-M:  Reading sequence
(e) Redundant links for server-side image maps
Replace with a new provision on keyboard operability. Requiring equivalent text links is one way to make server side image maps accessible but there are other ways. New provision proposed below. The need behind this one is covered by 3-S:
Keyboard Operation.
(f) Provide client side image maps
Since there is no area than cannot be defined with an available geographic shape, this provision essentially prohibits the ues of server side image maps. But they can be accessible as long as keyboard alternatives are provided. So the need behind this one is covered by 3-S:  Keyboard Operation.
(k) Provide a text-only page
A provision on alternatives is not needed because they can always be provided via equivalent facilitation. Note that this is still under debate in the subcommittee.
(l) Use of scripting languages
We no longer have technology specific provisions. User interfaces implemented in any technology, including scripts, must meet all applicable checkpoints. 3-S Keyboard Operation and 3-P:  UI Components are particularly applicable to UIs created with scripts.
(m) Use of applets or plugins
We no longer have technology specific provisions. User interfaces implemented in any technology, including scripts, must meet all applicable checkpoints. 3-S Keyboard Operation and 3-U:  AT Interoperability are particularly applicable to applets and
plug-ins.
(o) Skip repetitive links
When 3-O:  Information and Relationships is met, user agents can provide better means for efficient keyboard navigation. In WCAG 2.0, meeting the provision that is comparable to 3-O is sufficient to meet the WCAG 2.0 provision on bypassing repetitive blocks of content.
