Re: WCAG 2.1

There are a few points to consider.

- The 2.1 Criteria can strengthen requirements but cannot weaken one. Thus
to meet 2.1 you may change the level from AA to A but you cannot move from
AA to AAA. You may also add additional requirements to an existing SC.
Also, failure to meet 2.1 will not negate conformance to 2.0. If you want
2.1 conformance you must do more. This was in the TF''s  and WCAG's charges.

- At least on the LV task forces we are focusing on content. The ability to
restructure the presentation to a linear arrangement of elements is
completely achievable with content. Resizing text to much more than 200%
with word wrapping is entirely an issue of content. Here are some common
barriers that interfere with access.

* Fixed Top Banners
* Tabular structure that causes lines of enlarged text to run off the page
(Seen frequently in Webmail clients)
* RWD pages that prevent text enlargement
* Inline style specifications that disable cascading style sheets
* Use of background images for anything but decoration
* Multi-column format (Even worse when layout tables are used)
* Margins and padding that resize with font size
* Pages that do not allow restyling
* Use of HTML elements like <select> <option>, and input type radio that do
not support style changes.

Content that interferes with single column reconfiguration, element level
customization, control of line length and enlargement with word wrapping is
inaccessible content, and it is unnecessary.

There are user agent problems. The fact that change of font size loses your
place in the file using almost every user agent is not a problem of the
content author. We know the difference.

- The model of external AT works well for some disabilities. It is not too
effective for others. In the case of providing a single column interface
that enables very large print for people with acuity reduction and short
lines with normal print for people with peripheral field loss the solution
is entirely within the scope of content authors.
