Summary of public comments on Checkpoint/Guideline 3.3 as reported in Bugzilla December 17, 2003 Prepared by: John Slatin On 17 December 2003, Bugzilla found 13 bugs related to Checkpoint/Guideline 3.3. Ten of these referred to the June or September Working Drafts. The last three (#648-650) show the proposed plain language wording broken into three separate items. There have been no comments about the plain language proposal, either in Bugzilla or on the list, and it has not yet been discussed in the weekly teleconferences. The comments seem to fall under the following headings: Editoraial suggestions #381 Miscellaneous editorial suggestions Comments on June 24 WD by Harvey Bingham re: best practices and benefits. Suggests use of bulleted lists in place of long series in sentence-form (best practices), notes ambiguity in use of word "concrete" under examples. [The plain language proposals use bulleted lists rather than comma-separated series in sentence form, so I think this issue has been resolved. The word "concrete" is still used in Additional Measures/Strategies, however, and I'm not sure I have a better alternative yet. Some candidates include: specific, real, tangible, literal (as in the opposite of figurative), but all of these seem to pose the same problem-they're pretty abstract <grin>.] Difficulty of understanding what the checkpoint/guideline requires #419 Kynn Bartlett, Aug 2003, sarcastic comment about opacity of language; response by Wendy Chisholm Addressed (if not fully resolved) by plain language proposals #480 September 2003, Olivier Thereau: "not more than necessary" is not testable, tentative suggestion to reword checkpoint title to focus on "review" rather than "not more than necessary." [This point is addressed, if not yet fully resolved, by plain language proposals. See discussion of items 648-650 for details.] #513 Includes both editorial and substantive comments from Kansas Web Accessibility Committee, October 2003. 1. Editorial: change "supplement" to "supplemented"; 2. Editorial: label "Required success criteria is missing". 3. Substantive: "might be useful to describe proper and effective use of non-text content for the purpose indicated" These items are addressed by the plain language revisions. See discussion of #648-650 for details. Difficulty of defining and evaluating "complexity" #495 How to evaluate complexity of content October 2003, Greg Gay posts substantive two-part critique of 3.3. He 1. argues that it's inappropriate to include language as a criterion for accessibility. He argues that evaluating the complexity of written content is a specialized job for copy-editors rather than accessibility evaluators, that it would be costly and ultimately unreliable because subjective. Automated tools aren't adequate to the task and it's difficult to determine what the cutoff point below which the document fails would be. 2. notes that we should distinguish between "alternative formats" and simpler or less complex versions, noting that in our examples we talk about supplementing complex text with audio and/or visual illustrations but don't make clear that these are simplified representations. The second point can (and should) be resolved by modifying the examples to show how the supplemental content provides simplified representations of complex textual content. The first issue poses a philosophical problem about the scope of the guidelines themselves. This concern is picked up in the Access Board's comment that 3.3 crosses what they regard as the line between accessibility and usability (see next item). #569 Complexity is subjective October 2003, US Access Board argues that 3.3 belongs more properly to usability than accessibility and adds that "writing style" is "subjective" Additionally, Joyce Tikalsky suggests that these suggestions about writing style apply across all communications media and are too general for accessibility; suggests that the suggestions could be moved to a set of recommended guidelines about editing Web content. Some of these concerns are addressed though not fully resolved in the plain language proposals under Level 2 and Additional Measures, but testability remains a major concern as does the question of whether 3.3 goes beyond the scope of accessibility. What types of content should be included under 3.3 (specifically ASCII art, illustrations, sound) #382 (sound) August 2003, Harvey Bingham: suggests explicitly including synthetic speech (with variations of pitch, rate, etc.) as well as announcement of events. Not yet addressed; might be incorporated in strategies and examples, references to CSS 2.1 speech properties. #420 (ASCII art) August 2003, Kynn Bartlett: points out that ASCII art is text. I think This is moot in the plain language proposals, which don't mention ASCII art. #421 (Use of illustrations) August 2003, Kynn Bartlett critiques phrasing that reads "Designers need to be cautious" about "using illustrations." Kynn notes that this appears to discourage use of illustrations and argues that we shouldn't discourage that. Urges careful phrasing to avoid misinterpretation by others like the frequent misunderstandings of the WCAG 1.0 and 508 provisions about color. Resolved in plain-language proposals, which delete the cautionary note and specifically call for use of illustrations to clarify complex material. Proposals #430 Proposal 3, Checkpoint 3.3 August 2003, Lisa Seaman, on behalf of a group. This proposal, sent to the list and available at http://lists.w3.org/Archives/Public/w3c-wai-gl/2003JulSep/0244.html <http://lists.w3.org/Archives/Public/w3c-wai-gl/2003JulSep/0244.html> , forms the substance of Checkpoint 3.3 as it appears in the September WD, though portions of the proposal were altered as they migrated into the WD. Perhaps the most important concept that does not appear in the WD is the one that calls for "markup of key information that the user typically requires." Lisa notes that this requirement is "similar to 1.3" but differs in the important respect that it first calls for identifying important information and including it in structural markup, whereas 1.3 calls for using structural markup and making structure manifest: In my judgment, the proposal is clearer and perhaps more nearly testable than Checkpoint 3.3 as it appears in the September WD; the first plain language proposal (#648) took the WD as starting-point rather than this proposal, so does not include the item about identifying key information and incorporating it into structural markup. #648 Proposed wording for Guideline 3.3 November 2003 Items 648-650 re-frame Slatin's proposal for rewording Checkpoint 3.3 into three separate items. Item 648 (this item) presents the current and prposed wording for Checkpoint (now Guideline) 3.3, as follows: Current wording for Checkpoint 3.3 3.3 [E8] Content is no more complex than is necessary and/or is supplemented with simpler forms of the content. Proposed wording for Guideline 3.3 3.3 [E8] Use the clearest wording that is consistent with the purpose of the content. Provide summaries or paraphrases of complex material, and provide visual or auditory illustrations as appropriate. The proposed rewording eliminates the controversial phrase "no more complex than is necessary," but replaces it with one about consistency which may be equally difficult to test. The proposed rewording encourages the use of non-text content to supplement complex text. It does not explicitly call for simplified representations. The reference to summaries or paraphrases could be modified to call for these to be written in simpler language than the primary content, and a reference to call for simplified illustrations may be added as well. #649 Proposed wording for Guideline 3.3 Level 2 November 2003 Item 649 proposes rewording Success Criterion #1 for Checkpoint (now Guideline 3.3). This was part of the plain language proposal. The revision addresses at least some complaints about the difficulty of understanding the checkpoint. Some of these changes also address problems with testability raised in the comments. 1. The original wording of "A. familiarity of terms and language structure" would be replaced by "A. The resource uses vocabulary which is widely used by members of the intended audience." This replaces the vague "familiarity" with language that suggests a test. Note that Lisa Seaman's proposal would go even farther by calling for links to a specific lexicon or glossary. 2. The original "B. reasonableness of length and complexity of sentences" would be replaced by language that suggests possible tests: sentence length and complexity should be consistent with practices recommended by widely used textbooks about writing in the relevant discipline 3. The proposal replaces vague wording ("C. coherence of paragraphs (and sensibility in length)") with more a more testable criterion: "paragraphs develop a single topic or subtopic" (the issue of length is not addressed here; the Seaman proposal calls for a maximum of 7 sentences per paragraph). 4. The call for "clarity of headings and link text when read out of context" is modified to include specific situations where headings and link text must be understandable, e.g., in lists of links and headings reported by screen readers 5. The item about accuracy of page titles is now written in sentence form and calls for page titles to be unique and informative (consistent with Seaman proposal) 6. The item about care in using all caps is deleted as being categorically different from other criteria in this list. The deletion is NOT consistent with the Seaman proposal. 7. The criterion about the use of (unspecified) non-text content for clarification is replaced by wording that calls for use of page design as well as graphics, audio, video, and animation to clarify complex material. This specifies types of non-text content but does not address the concern about providing less complex representations of complex content; the item could be reworded to address that concern. There is still a testability issue: the proposal replaces "where they felt it was appropriate" with "as necessary," but does not indicate how necessity should be determined. This is probably decidable only through user testing, though perhaps user testing could yield generalizable results/guidelines for recognizing complexity. #650 Proposed wording for Guideline 3.3 Strategies November 2003 This item, also part of the plain language proposal for 3.3, proposes new wording for the list of additional measures/strategies for achieving greater clarity and simplicity. It attempted to organize the list under several headings and to suggest specific practices that are or could be made testable. For example, it suggests using style manuals, dictionaries, and other reference tools (could be strengthened by specifying that these should be used to standardize citation formats, spelling, punctuation, etc.; and by requiring the site to declare what manuals, dictionaries, etc., have been used). It also suggests testing comprehension with real users, including people with reading disabilities (this would presumably compound Greg Gay's objection about the cost of meeting such a requirement). The proposal also offers criteria for determining when or whether to use a controlled language and/or plain language lexicon, e.g., if the document is intended for translation or if it presents highly technical information to a non-technical audience or to non-native speakers. Item 6 in the list does not satisfy Harvey Bingham's concern about the ambiguous use of the word "concrete" as an antonym for "abstract." Slatin suggests moving the items grouped under the heading "Instructions and operable content" to Guideline 2.5, which has to do with reducing the likelihood of error and making it easier to recover. Most of these items are readily testable and come appropriately under the rubric of operability. Moving them to 2.5 as Level 2 criteria would raise their importance and make it more likely that sites would follow these guidelines. "Good design is accessible design."
