The exercise of replacing difficult terms such as "programmatically determined" with the proposed definition led to some interesting results. In most cases it seemed to work well. However, in the case of Guideline 3.2 L2 SC1, the experiment yielded the following: <blockquote> <include definition in success criterion> 1. Any extreme change of context is implemented in machine-readable form (e.g., in markup, metadata, or a data model). </include definition in success criterion> </blockquote> I'm concerned that this doesn't indicate clearly enough the *result* we're looking for: providing advance notice of extreme changes of context and/or making it clear that users shouldn't be subject to *involuntary* changes of context such as meta redirect/refresh (both of which can be accomplished through valid HTML 4.01 markup or in metadata) I don't have a proposal at this point, but it seems like something we need to work on.

Derived programmatically (GL 1.3 L1 SC1 and SC2) 2. Programmatically identified (GL 3.2 L2 SC1) 3. Programmatically determined (GL 3.1 L2 SC2, and SC6) 4. Programmatically located (GL 3.1 L1 SC2 and GL 3.1 L2 SC1) As I understood the discussion, people who participated in the call agreed about the following (I don't remember whether there was formal consensus): 1. The four terms should be reduced to two: a. Proposal: replace "derived programmatically" and "programmatically identified" with "programmatically determined." 2. Proposal: Define programmatically determined to mean "is available in a standard machine-readable form (e.g., in a standard markup, data model or metadata)" 3. Further attempts to define "programmatically located" should be deferred until after the 11 August joint call with PFWG. Further discussion off-list about potential ambiguities of the word "standard" led to a further refinement of the definition of "programmatically determined": Programmatically determined="available in machine-readable form (e.g., in markup, metadata, or a data model)." There was a related discussion off-list about the term "explicitly associated" (used in 1.1 L1) The question was whether an association that could be recognized by humans but not by user agents would satisfy the intent of "explicitly associated." The feeling was that an association that could be recognized only by a human and not by a user agent was not good enough. Based on these discussions, I've taken the affected success criteria and (1) replaced the now-obsolete terms (derived programmatically and programmatically identified) with programmatically determined and (2) replaced programmatically determined with the definition language. I've done the same thing for 1.1, the only occurrence of "explicitly associated" in the 30 July WD [2]. Success criteria that currently contain the phrase programmatically identified Guideline 3.2 L2 SC1 <current> 1. Any extreme change of context is implemented in a manner that can be programmatically identified. </current> <replace programmatically identified> 1. Any extreme change of context is implemented in a manner that can be programmatically determined. </replace programmatically identified> <include definition in success criterion> 1. Any extreme change of context is implemented in machine-readable form (e.g., in markup, metadata, or a data model). </include definition in success criterion> [1] http://lists.w3.org/Archives/Public/w3c-wai-gl/2004JulSep/0318.html <http://lists.w3.org/Archives/Public/w3c-wai-gl/2004JulSep/0318.html> [2] http://www.w3.org/TR/WCAG20/ <http://www.w3.org/TR/WCAG20/> "Good design is accessible design."
