Hello, Congratulations on your Last Call. One comment that you may have received from others: If the principles [1] were maintained outside the guidelines [2], then the guidelines might be easier to find and comprehend. The guidelines would then have thirteen whole numbers. Maybe [1] could say which guidelines developed from which principle. Below is just a text outline. I wonder if the spec adheres to its subject -- the guidelines -- if implementers may find the guidelines easier to follow over time. Hope this helps. For [1]: ======== * Principle 1: Content must be perceivable (Guidelines 1-4). * Principle 2: Interface components in the content must be operable (Guidelines 5-9). * Principle 3: Content and controls must be understandable (Guidelines 10-11). * Principle 4: Content should be robust enough to work with current and future user agents (including assistive technologies) (Guidelines 12-13). For [2]: ======== * Guideline 1: Provide text alternatives for all non-text content. * Guideline 2: Provide synchronized alternatives for multimedia. * Guideline 3: Ensure that information and structure can be separated from presentation. * Guideline 4: Make it easy to distinguish foreground information from its background. * Guideline 5: Make all functionality operable via a keyboard interface. * Guideline 6: Allow users to control time limits on their reading or interaction. * Guideline 7: Allow users to avoid content that could cause seizures due to photosensitivity. * Guideline 8: Provide mechanisms to help users find content, orient themselves within it, and navigate through it. * Guideline 9: Help users avoid mistakes and make it easy to correct mistakes that do occur. * Guideline 10: Make text content readable and understandable. * Guideline 11: Make the placement and functionality of content predictable. * Guideline 12: Support compatibility with current and future user agents (including assistive technologies). * Guideline 13: Ensure that content is accessible or provide an accessible alternative.
