WCAG 2.0 Checklist Concept - Consolidated Applicability Conditions

WCAG 2.0 Checklist Concept - Page 3 of 3

Based on your answers the questions on pages one and two, the following techniques are required for level A conformance with WCAG 2.0.

Summary:

You indicated that:

you are using HTML and CSS

non-text content is included in the content for which you are making a claim

your content includes one or more img and object elements

your content does not include live audio-only or video-only content

etc...

[Issue - This list above has the potential to be quite long. We may want to make it possible to expand/collapse this list.]

The following checklist items are organized by guideline and success criteria. Each checklist item must be marked "true" in order to claim conformance to WCAG 2.0.

Principle 1

Guideline 1.1 Provide text alternatives for all non-text content.

Level 1 Success Criteria

Editor's Note: The following is a listing of success criterion for level 1 of guideline 1.1. Each item listed below the criterion would be required to be true in order to pass the criterion. Note that this prototype is a non-functional mockup of how a checklist might look and is not yet complete.

Checklist Item

To do notes

Notes:

This proposal necessitates a one to one mapping between checklist items and tests and one to many relationship between techniques and checklist items. Each checklist item may have multiple techniques associated with it such that when viewing techniques one might see multiple related checklist items.

Do general techniques need short a handle/numbering scheme?

HTML 9.3 - seems like this is a general technique, overlaps with GEN (text-equiv-functional)

HTML 11.1 - propose that we remove mappings to guideline 1.1 and 3.2 - keep primary mapping to 2.1 (keyboard operation is reason to recommend use of client-side. Serverside is covered in (to-be-written) alternate navigation mechanism technque.

HTML 12.4 - propose that the only mapping should be to level 1, SC5 since the type of content included by object will vary

HTML 14.4 - map to guideline 1.3 per Feb. 4, 2005 call? (assertion is that frames are presentational markup that implies structure, thus conveying structural information falls under 1.3)

noembed and applet are not part of current specs - do they trip 4.1? should the be included in required techniques? repair techniques?

1.1 L1 SC4 - seems like something that wouldn't (necessarily) need a general technique since how to do it is so technology specific. Perhaps a general technique that has a checklist item designed to verify that non-text content is "decorative"?

HTML 16.1 - are scripts functional or informational? Are there cases where we would need to require <noscript> for both types? Additionally, are there scripts that would be designed to ignored by AT (and is leaving <noscript> out how we recommend indicating that they should be ignored)?

CSS 6.1 - included under information, but could also be an issue under visual art/sensory experience. include in both places?

past notes on checklist prototyping

"task" is not well defined. do current techniques "tasks" fit better as titles for techniques?
