***1. In response to this comment by Eric Hansen: > PART 2: PROPOSED REVISIONS FOR THE PAGL DOCUMENT > > Notes are found between square brackets and headed by the word "NOTE". The > notes are my (Eric Hansen's) side comments and are not for inclusion in the > PAGL document. Daniel Dardailler wrote: "Could you indicate which version you used as your starting point, and whether or not all your changes are indicated with a following [NOTE] comment. Without that information, it's hard to tell what is your contribution." Eric Hansen's current response: It is all my contribution. I just wrote it on the basis of the the way I see the guideline document and its purpose. Because it was written essentially from scratch you would probably not find any version of the guidelines that parallels what I have provided. In fact, any parallels would be due either to coincidence or simply to my having absorbed material from the guidelines text from having read it a number of times. Text within the brackets, [NOTE. etc., etc.] is not intended for inclusion in the guidelines document. By the way, I think that all my references to specific material in the document should be correct for the 4 January 1999 version of the guidelines. ***2. In response to this comment by Eric Hansen: > 2.A. PROPOSED INTRODUCTORY PORTION OF GUIDELINES DOCUMENT > > Purpose > > The Page Authoring guidelines document is designed to help Web authors > improve the accessibility of Web sites for people with disabilities. The > document also indicates how following the guidelines can also make Web > sites more accessible and usable to individuals without disabilities. Daniel Dardailler wrote: "I still strongly feel that we should sell these guidelines as being primarily for solving the issue of Device Independence wrt access of Web Content (output and input)." Eric Hansen's current comment: I think that the guidelines should be sold on the way they will help people access information: e.g., access for PEOPLE with disabilities, improved access and usability for USERS of diverse Web browsers (handheld, mobile), etc. Personally, I prefer not to dilute the emphasis on people with disabilities. ***3.

Daniel Dardailler wrote: "I'd put point 2 first and add "(e.g. better search engine results) in point 3." Eric Hansen's current comment: Again, I like emphasizing people with disabilities and I think that listing people with disabilities reflects the actual underlying nature of the document. For example, isn't it true, as I have assumed in my explanation of assumptions (Part 2), that the impact ratings that influence the priority (imperative) ratings are ONLY the ones that relate to disability groups? How could it be otherwise? The list of "device-based" groups (e.g., "users of handheld devices", "users of telephone-based browsers") is, in principle, infinite. And perhaps many of the devices that would be affected have not even been invented yet. That means it is hard to actually generate impact ratings for those device-based groups. One just does not really know to what extent all those device-based groups would be affected by violation of a single checkpoint. On the other hand, there is only a finite number of major disability groups that could have been considered in generating impact ratings. These groups can and should be named. Generating impact ratings (at least for the groups most impacted) by violation of each checkpoint is doable. To summarize, I think that accessibility for people with disabilities properly underlies the priority (imperative) ratings, so that it makes sense to list them first. I like your idea of emphasizing the guidelines' potential for improving searching and finding (via engines and other means). I think that I might suggest inserting the following point after the 2nd point: "* Will improve users' ability to quickly find information, particularly information about multimedia and interactive objects." That point exploits the guidelines' emphasis on alternative content, etc. ============================= Eric G.
