Re: Rethinking A1.2 and A2.3 - was Re: Looking at A.2.3

Hi Michael,

So am I right in reading your email as having these proposed rewordings?

A.1.2.1 There must be and underlying accessibility architecture on the
platform upon which the authoring tool is to be executed

A.1.2.2 User interface chrome, content display, and other non-web-based
authoring user interfaces implement and leverage the accessibility
architecture wherever possible

A.1.2.3 If any non-Web-based authoring user interface functionality is
not supported by the implemented accessibility platform architecture(s),
then a separate accessible alternative for that functionality that is
supported by the implemented accessibility platform architecture(s) is
provided and a description of the inaccessible functionality appears in
the conformance claim.

And...

Guideline A.2.3 [For the authoring tool user interface] Ensure that the
interface is enabled for alternative presentations.

-------------------------------

If so, I  like the direction...but I'm not sure we can require A.1.2.1.

Cheers,
Jan
