Draft re Device Adaptation
This closes my Action-1512

DRAFT
The following comments are forwarded on behalf of WAI Protocols & Formats Working Group regarding the CSS Device Adaptation specification at:

http://www.w3.org/TR/css-device-adapt/

PF believes the methods provided in this specification, both via metatags and
via CSS markup, to inhibit a users ability to zoom screen content are enimical
to good accessibility practice and may violate the WCAG requirement that text
can be enlarged by at least 200%.

[Inject WCAG href]

Idealy any user should be able to zoom, in our view. We see this affecting accessibility for users who experience situational or incipient accessibility concerns--in other words users who are likely not users of assistive technology and who probably would not self-identify as persons with disabilities.


We would like to know more concerning the degree to which this features may already be implemented in user agents.  We thank you in advance for any data you can supply on this point.

While we are not directly asking this capability be removed from the specification at this time, we do believe it important, at a minimum, that the specification note the accessibility impact of these methods, and advise authors that, should they inhibit zoom, they would need to use some other approach to satisfy the WCAG requirement noted above.

Looking forward to your comments and response,
/DRAFT
