Eric has proposed the following changes to the introductory material in the guidelines section: From the principles of accessible content listed in the old section 2: Add to Separate structure and content from presentation. the following: This separation makes it easier to for user agents (e.g., browsers and related assistive technologies) to generate of several different renditions (presentations) (e.g., synthesized speech, braille, visual display) from the same underlying representation of the content and structure. Replace Ensure that accessible equivalents are available for all objects that may not otherwise be accessible (e.g., text, audio descriptions for video) With Provide _ text equivalents_ for all objects that are not otherwise be accessible (e.g., images, movie, audio clips, applets, etc.). Textual representations are essential because they can be flexibly rendered in so many accessible ways (synthesized speech, braille, and visually-displayed text). Add to Provide consistent structure and navigation the sentence Such consistency facilitates comprehension and navigation. If we keep the Techniques document in the form of the guidelines document with additional material included, then it might be worth exapnding the introduction to the guidelines material and including such additions. However in the guidelines themselves I feel that these explanations are unnecesssary, since these are in any case mere pointers to the essential ideas which are spelled out in WCAG, and with which the developers will necessarily become familiar from that document. charles --Charles McCathieNevile mailto:charles@w3.org phone: +1 617 258 0992 http://www.w3.org/People/Charles W3C Web Accessibility Initiative http://www.w3.org/WAI MIT/LCS - 545 Technology sq., Cambridge MA, 02139, USA
