UAAG Comments

Hi guys, no the whole I think this is very good. But here are a few comments...

Missing 'an' in the sentence after the comma
1.1.3 Replace Non-Text Content: The user can request a placeholder that incorporates recognized text alternative content instead of recognized non-text content, until explicit user request to render the non-text content. (Level A)

1.4.2 and 1.4.3 need a space between the : and (

1.8.14 is a good idea but I think we need to make it clear that persistence is not guaranteed if the page elements have changed  and there needs to be some way to notify people that the marked content has changed or been lost. Also typo space required between . And (
1.8.14 Provide Webpage Bookmarks: The user can mark items in a webpage, then use shortcuts to navigate back to marked items. The user can specify whether a navigation mark disappears after a session, or is persistent across sessions.(Level AAA)

For 1.10.1 are we assuming that close elements will be close in the DOM. I'd think this would be hard based on the visual rendering, and would require some idea of the semantics of the association. I'd also think that a label to a form element could be close in  DOM for distant in the visual rendering based on the CSS, how is this handled?

For the understandability principle, then isn't this a little all encompassing. There is nothing about simple language usage or graphic usage for people with a learning disability. So my question is understandable to whom?

Finally, 4.1.7 is about making API Calls be timely such that delays aren't perceived by users, but this is difficult if the software interfaced to us not timely, people may the perceive a delay. I think this needs to be a little more explicit.

Cheers
