Term: Programmatically determined - The definition for "programmatically determined" is "determined by software from data provided in a user-agent supported manner such that the user agents can extract and present this information to users in different modalities". What is the definition by "user agent supported manner"? Does this mean that even if only one user agent on only on version of an operating system can extract the information then it complies? What about people with colour blindness? If faced with an image they can't interpret due to colour blindness, they could just use a colour picker tool which will tell them the hex values of each pixel and determine the contents of an image that way.

Proposed Change:

Redefine SC that use the term programmatically determined; Related issues: 756 1502
(space separated ids); WG Notes: [TEAMA] Discussed in the 19 April 2007 telecon: accepted as proposed http://www.w3.org/WAI/GL/2007/04/19-wai-wcag-minutes.html {partial accept} Response: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jul/0128.html New issue: http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=2336; Resolution: The notion of "programmatically determined" is basic to the success criteria that use it; we don't see a way of redefining those success criteria not to use the concept. The first issue in "programmatically determined" is making sure that the information is represented in the technology in a way that is clear and unambiguous within the capabilities of that technology. Many of the most serious issues addressed by requiring that information be programmatically determined have to do with authors implying information via visual presentation, rather than encoding it explicitly in the technology. We put extensive work into the difficult issue that you identify, of "which assistive technology"? The basic answer is that it is the assistive technology available to the audience. Individual techniques identify issues with specific versions of user agents and assistive technology, so that authors can make informed decisions about whether the techniques are acceptable for their audience.; (Please make sure the resolution is adapted for public consumption)
