Gregg suggests: <gregg> Scoping can include and exclude parts of a site. However processes and authored units must be evaluated in their entirety. If part of a process unit does not conform (at some level), than no conformance (at that level) can be made for any web unit in the process. The same applies to authored units. </gregg> <slightEdit> Scoping can include and exclude parts of a site. However, processes and authored units must be evaluated in their entirety. If part of a process unit does not conform at some level, then conformance at that level cannot be claimed for any web unit in the process. The same applies to authored units. </slightEdit> "Good design is accessible design." Dr. John M.

It was pointed out that the second sentence in the following was almost unreadable. Scoping can include and exclude parts of a site. But if any Web unit that is part of an authored unit or part of a process or does not meet WCAG 2.0 at some conformance level then no Web unit that is part of the authored unit or part of the process can claim conformance at that level. Suggested rewording: Scoping can include and exclude parts of a site. However authored units and processes must be evaluated in their entirety. If part of an authored unit (or a process) does not conform (at some level), than no conformance (at that level) can be made for any web unit in the authored unit (or the process). Still a bit complicated. Could break it up further. Scoping can include and exclude parts of a site. However processes and authored units must be evaluated in their entirety. If part of a process unit does not conform (at some level), than no conformance (at that level) can be made for any web unit in the process. The same applies to authored units.

Below are three things - that if we agree on - should be clear in the last call document. 1) We intend for a page to be accessible without requiring that all links on a page lead to accessible content. (otherwise one could never link to content out of their control). 2) We want to allow people to separate content on their website and make claims for some but not all of it. (someone else may require accessibility but we do not). 3) We also decided that a process shouldn't be accessible up to its final stages and then go inaccessible. Like everything in a store but the checkout. To fix this - I am suggesting that we add the following to our scoping section which currently reads <current text> Scoping of conformance claims Conformance claims can be limited, or "scoped," to pertain to only some parts of a Web site. All conformance claims, however, must be directed to a URI or a range of URIs. Scoping to exclude a particular type of content (for example, images or scripts) from a site is not allowed since it would allow exclusion of individual success criteria. Scoping by URI to exclude sections of a site is allowed so that authors can make claims for just some parts of a site. Example 3 above is a scoped conformance claim. <end of current text> <start proposed text to add to the end of the above> Scoping can include and exclude parts of a site. But if any Web unit that is part of an authored unit or part of a process or does not meet WCAG 2.0 at some conformance level then no Web unit that is part of the authored unit or part of the process can claim conformance at that level. Example 1: An online store has a series of pages that are used to select and purchase products. All pages in the sequence must conform in order to claim conformance for any page that is part of the sequence. Example 2: A site has a collection of videos for which it was not required to and did not want to claim accessibility. The site can locate the videos in one location (e.g. example.com/movies) and then write a conformance claim for the site or section of the site that excludes that location. As long as the pages on the site only linked to the videos (and did not embed them in a Web page or other web unit) the conformance claim would be valid. Linking to inaccessible content does not make a page inaccessible. Only if that content is rendered together with the web page (or other web unit) or if the content is itself a Web unit within the set of URIs to which the conformance claim applies (or if the Web unit is part of a process for which a claim is made) would it have to meet the guidelines in order for the claim to be valid. This scoping provision does not preclude an organization, customer, or government from requiring that all parts of a site be accessible or meet some standard including WCAG. WCAG does not require that full websites conform, although that is certainly seen as desirable. A conformance claim only requires conformance for Web Units that are in the URI set described in the claim. <end proposed additional text> Gregg ------------------------ Gregg C Vanderheiden Ph.D. Professor - Depts of Ind.
