Hello, I haven't finished reading the AU techniques document that's part of last call [1] but I wanted to send these comments anyway. I will reserve most editorial comments for another review. 1) The document contains very little in the way of explanatory prose. This means that I think it will not help a reader unless that reader is a very informed developer. I think that this draft contains sufficient information for the Guidelines to become a Recommendation, but I think the Techniques document needs to be restructured with more prose, more explanations, and more rationale. 2) Under checkpoint 1.1: a) Bullet 1: Provide options for accessibility information such as equivalent alternatives to be included whenever an object is added to a document. I think the case of alternative text should be singled out. I think "such as" weakens a technique since the reader has no other place to turn at this point. There should be concrete examples in place of generalities. b) Bullets 3 and 4 refer to WCAG 1.0 Guidelines and Techniques. However, these are covered by checkpoint 1.2, so I suggest moving these techniques to checkpoint 1.2 c) I think techniques for W3C languages should be listed clearly, as in: * Accessibility of HTML * Accessibility of CSS * Accessibility of SMIL etc. The current wording obscures this. 3) Under checkpoint 1.2 There should be no techniques in this checkpoint other than references to WCAG 1.0. I feel quite strongly about this since attempts to include information will necessarily be incomplete and risk deviating from WCAG 1.0. If the working group has suggested techniques, those should be sent to WCAG. 4) Under checkpoint 1.3 a) Template is undefined in the checkpoint text. b) Please refer to "navigation mechanisms" instead of "navigation schemata" for consistency with other WAI Guidelines. 5) Under checkpoint 1.4 a) The second bullet talks about using "title" for descriptions of images. This is not recommended by WCAG. b) Fifth bullet: WYSIWYG is undefined. 6) Under checkpoint 2.1 a) (editorial) Text in the first bullet is repeated. 7) Under checkpoint 2.2 a) I think the checkpoint should read: "Ensure that generated markup conforms to a published specification." b) I don't understand the third bullet. It may mean: "Use schemas to describe transformations from one markup language to another." This may also be done with the XSL Transformation language. 8) Under checkpoint 2.3 a) I don't understand the example about frames in the first bullet. It's not clear whether it means "Don't create a frame document with NOFRAMES" or "Don't use a DTD for frames without NOFRAMES". b) The third bullet should qualify that the statement applies to the time of publication of the AU Techniques Document. 9) Under checkpoint 3.1 a) What is the rationale of the second bullet on uppercase letters? b) Fifth bullet: say "natural language" 10) Under checkpoint 3.2 a) In first bullet, say "alternative equivalents" instead of "alternative information". b) In the second bullet, say "image" instead of IMG and refer to a text equivalent instead of alt text. 11) Under checkpoint 3.3 a) The second bullet on clip art long descriptions needs more explanation. b) In third bullet, refer to captions, not "video description files". c) In fifth bullet, there is reference to pre-written descriptions that will circulate on the Web. The same was said of shared style sheets and I don't think in reality that that is the case. I don't have any data to back up that statement, however. 12) Under checkpoint 3.4 a) The first bullet is too detailed and difficult to understand in its current wording. b) In the fourth bullet, there is reference to "alternative information mechanism" followed by the acronym "ACM". How do the two relate? Should it be AIM? - Ian
