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.
