Dear Inclusion Europe, Thank you for your comments on the 17 May 2007 Public Working Draft of the Web Content Accessibility Guidelines 2.0 (WCAG 2.0 http://www.w3.org/TR/2007/WD-WCAG20-20070517/). The WCAG Working Group has reviewed all comments received on the May draft, and will be publishing an updated Public Working Draft shortly. Before we do that, we would like to know whether we have understood your comments correctly, and also whether you are satisfied with our resolutions. Please review our resolutions for the following comments, and reply to us by 19 November 2007 at public-comments-wcag20@w3.org to say whether you are satisfied. Note that this list is publicly archived. Note also that we are not asking for new issues, nor for an updated review of the entire document at this time. Please see below for the text of comments that you submitted and our resolutions to your comments. Each comment includes a link to the archived copy of your original comment on http://lists.w3.org/Archives/Public/public-comments-wcag20/, and may also include links to the relevant changes in the WCAG 2.0 Editor's Draft of May-October 2007 at http://www.w3.org/WAI/GL/WCAG20/WD-WCAG20-20071102/ Thank you for your time reviewing and sending comments. Though we cannot always do exactly what each commenter requests, all of the comments are valuable to the development of WCAG 2.0. Regards, Loretta Guarino Reid, WCAG WG Co-Chair Gregg Vanderheiden, WCAG WG Co-Chair Michael Cooper, WCAG WG Staff Contact On behalf of the WCAG Working Group ---------------------------------------------------------- Comment 1: Reading level changed to primary education level Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0260.html (Issue ID: 2156) ---------------------------- Original Comment: ---------------------------- Most people with cognitive disabilities do not complete lower secondary education. In order to provide accessibility for the large majority of this group, texts must be as easy to read as possible. Since this success criterion is of paramount importance for people with cognitive disabilities, the reading level must be changed to be equivalent to primary education. Proposed Change: New wording for success criterion 3.1.5: When text requires reading ability more advanced than the PRIMARY education level, supplemental content or an alternate version is available that does not require reading ability more advanced than the PRIMARY education level. --------------------------------------------- Response from Working Group: --------------------------------------------- The working group explored the impact of changing SC 3.1.5 to using a primary education reading level. We were able to find very few examples of text on the internet that was written at this reading level, even when text was targeted at early primary school students. >From the examples that we were able to find, we think that this reading level target would limit authors severely and could not be satisfied for most content. We are also concerned that while reading level is a testable property of text, it is a fairly crude measure of how easy the content is to understand. We think that the needs of people with cognitive disabilities will be better met if authors follow the advisory techniques on using clear and easy to understand language, rather than try to write at an unrealistic reading level. ---------------------------------------------------------- Comment 2: Include criterion 3.1.5 in levels A and AA Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0302.html (Issue ID: 2157) ---------------------------- Original Comment: ---------------------------- To be able to access content in easy-to-understand language is of paramount importance for people with cognitive disabilities. It is in fact the core success criterion for this group of disabled people that must be met by all public websites. Therefore, it must be associated with level A and not only with level AAA. Proposed Change: Include success criterion 3.1.5. also in levels A and AA. --------------------------------------------- Response from Working Group: --------------------------------------------- Because of the tighter limits that this success criterion places on content, we feel it is appropriate at level AAA. Many legal documents cannot have alternative or supplemental content, and cannot be expressed in language at the primary level. ---------------------------------------------------------- Comment 3: Clearly identify supplemental content or alternate version Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0303.html (Issue ID: 2158) ---------------------------- Original Comment: ---------------------------- People with cognitive disabilities have difficulties in reading and understanding text. This has been recognized in success criterion 3.1.5. This also means that they have difficulties identifying on a website which of the contents is the supplemental content or alternate version that would be accessible for them. Therefore, supplemental content or an alternate version must be clearly identified as being accessible for people with cognitive disabilities without requiring them to read the whole text. This can be done for example by using the European Easy-to-Read Logo (www.inclusion-europe.org/etr) that is already used for this purpose in many European countries. A logo comparable to the logo for physical access has the advantage to be language independent. Proposed Change: To insert a new success criterion 3.1.5.bis or modify the criterion 3.1.5 as follows: Supplemental content or alternate versions for people with cognitive disabilities must be clearly identified by an access symbol and must be accessible from the referring page by one click. Example of success criterion 3.1.5.bis: Website of the European Commission, DG Employment and Social Affairs at http://ec.europa.eu/employment_social/fundamental_rights/index_en.htm --------------------------------------------- Response from Working Group: --------------------------------------------- We have added "clearly marked" to SC 3.1.5 so that it reads: "When text requires reading ability more advanced than the lower secondary education level, clearly marked supplemental content or an alternate version is available that does not require reading ability more advanced than the lower secondary education level." We have also added an advisory technique: "Clearly marking, by use of text or icon, content which has been optimized for easy reading (future link)" We are not mandating any particular markings since we do not want to limit the use of this technique. ---------------------------------------------------------- Comment 4: Symbols illustrating texts can be ignored by assistive technology Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0304.html (Issue ID: 2159) ---------------------------- Original Comment: ---------------------------- To make texts more accessible for people with cognitive disabilities, it is common practice to illustrate each paragraph with a symbol that summarizes the main idea of the text next to it. This communication symbol does not provide any supplementary information to a person who can read the text without any difficulties for understanding it. Proposed Change: To change the exceptional situation 4 listed under success criterion 1.1.1 as follows: "Decoration, Formatting, Invisible, Communication Symbols: If non-text content is pure decoration, or used only for visual formatting, or if it is not presented to users, or if it is a communication symbol illustrating the main idea of a text for better understanding by people with cognitive disabilities, then it is implemented such that it can be ignored by assistive technology. Inclusion Europe also proposes to add the following sentences to the explanations: "Providing communication symbols to illustrate texts is an effective method for many users, including those with cognitive disabilities. This provision should not discourage those types of cues as long as the communication symbols can be ignored by assistive technology." --------------------------------------------- Response from Working Group: --------------------------------------------- We agree that supplementing text with pictures is sometimes helpful to people with cognitive disabilities and we have a sufficient technique (G103) for Success Criteria 3.1.5 to do that. We think it is problematic however to allow non-decorative graphics to be marked so that their existence would be ignored by people using screen readers. It would become a loophole that could adversely affect accessibility for blind people. We believe that they should both be visually presented for those who can see and presented via alternate text for those who cannot. If the alternate of the graphic is completely explained by text that is on the page, then there can be a short alternate text that refers to the text on the page. Technique G74 covers this approach. We have adjusted the title of G103 to "Providing visual illustrations, pictures, and symbols to help explain ideas, events, and processes" ---------------------------------------------------------- Comment 5: Human testers should always be persons with disabilities Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0305.html (Issue ID: 2160) ---------------------------- Original Comment: ---------------------------- In the organizational section, it is stipulated that "some WCAG 2.0 success criteria require human testers for part or all of the test". Inclusion Europe would like to emphasize that those human testers must always be people with different kinds of disabilities themselves. Proposed Change: To change the text of the second paragraph of the point "Success Criteria" under Organization of the WCAG 2.0 document as follows: All WCAG 2.0 success criteria are written to be testable. While some can be tested by computer programs, others require human testers for part or all of the test. Human testers must always be persons with disabilities themselves. --------------------------------------------- Response from Working Group: --------------------------------------------- A methodology for conformance evaluation requires the involvement of human testers, but WCAG 2.0 does not define requirements with regard to such an evaluation methodology. While we encourage authors to test their Web pages with a wide variety of users, including users with disabilities, this is not necessary to conform to WCAG. Our current intro has been shortened and there is only a part of single sentence that mentions testing as follows. "WCAG 2.0 builds on WCAG 1.0 [WCAG10] and is designed to apply broadly to different Web technologies now and in the future, and to be testable with a combination of automated testing and human evaluation." However in our Understanding WCAG document we go into more detail as follows: "All WCAG 2.0 success criteria are written as testable criteria for objectively determining if content satisfies them. Testing the success criteria would involve a combination of automated testing and human evaluation. The content should be tested by those who understand how people with different types of disabilities use the Web. "Testing and testable in the context refer to functional testing, that is verifying that the content functions as expected, or in this case, that it satisfies the success criteria. Although content may satisfy all success criteria, the content may not always be usable by people with a wide variety of disabilities. Therefore, usability testing is recommended, in addition to the required functional testing. Usability testing aims to determine how well people can use the content for its intended purpose. It is recommended that users with disabilities be included in test groups when performing usability testing." ---------------------------------------------------------- Comment 6: Replace example 4 Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0306.html (Issue ID: 2161) ---------------------------- Original Comment: ---------------------------- The Microsoft Word Readability Scores for the text provided in the example 4 (Starting with "In a dazzling and dramatic portrait...") show a Flesch-Kinkaid score of 9.9 and not of 6.9 as mentioned in success criterion 3.1.5. The example should be replaced. On the website www.inclusion-europe.org, there are plenty of texts and publications with a Flesch-Kinkaid score lower than 7. Any of them can be used as example. Proposed Change: Change example text in success criterion 3.1.5. On the website www.inclusion-europe.org, there are plenty of texts and publications with a Flesch-Kinkaid score lower than 7. Any of them can be used as example. --------------------------------------------- Response from Working Group: --------------------------------------------- Thank you for catching this error. We have replaced this example with an example at an appropriate reading level. ---------------------------------------------------------- Comment 7: Mention of the Microsoft Word Readability Formulas Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0307.html (Issue ID: 2162) ---------------------------- Original Comment: ---------------------------- Microsoft Word is making readability formulas available and they are easy to access. Mentioning this in the paragraph speaking about those formulas will help people who are trying to find for which education level they have written their texts. Proposed Change: Sentence to be added in the paragraph about readability formulas (last paragraph before level education table): Microsoft Word Readability Formulas are available on each computer when running the spell checker if you specify in the options of this engine that you want to have the statistics when it has finished to check your documents. --------------------------------------------- Response from Working Group: --------------------------------------------- we have added the following Sentence in the paragraph about readability formulas "Readability formulas are available for at least some languages when running the spell checkers in popular software if you specify in the options of this engine that you want to have the statistics when it has finished checking your documents." ---------------------------------------------------------- Comment 8: Addition of a related resource Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jun/0308.html (Issue ID: 2163) ---------------------------- Original Comment: ---------------------------- European Guidelines on how to write text in an easy-to-read format have been written and translated into twelve European languages. They are presently under revision, but they are still an excellent resource for anybody who would like to write content in a way that is accessible for people with cognitive disabilities. Proposed Change: Add in the Related Resources of the Success Criterion 3.1.5. - European Easy-to-Read Guidelines. Inclusion Europe, Brussels, 1998 (under revision). Available in eleven European languages at www.inclusion-europe.org/etr. - European Easy-to Read Logo. Inclusion Europe, Brussels. www.inclusion-europe.org/etr. --------------------------------------------- Response from Working Group: --------------------------------------------- The URIs in your comment, www.inclusion-europe.org/etr, don't appear to be valid. However, we found other reference to this work at http://www.osmhi.org/?page=139 and http://www.osmhi.org/contentpics/139/European%20Guidelines%20for%20ETR%20publications%20(2).pdf and we have included these references.
