This is the format of the comment form used by WCAG [http://www.w3.org/WAI/WCAG20/comments/guidelines.php]. Let's use this as a general structure for our musings on the list. When we have reached consensus on an item, it will be easier to transfer to the actual form and submit it. Name: Jim Allan Email: jimallan@tsbvi.edu Affiliation: Texas School for the Blind and Visually Impaired Item Number: Success Criteria 1.3.1 1.3.3 1.3.4 2.4.8 3.1.1 3.1.2 4.1.2 4.1.1 ("parsed unambiguously") Appendix A: Glossary Comment Type: Technical (or Wording) Comment (Including rationale for any proposed change): "Programmatically Determined" is a user agent function. the language in checkpoints seems to point more at what a UA should do rather than what the author should do or provide. Proposed Change: <old> 1.3.1 Information and relationships conveyed through presentation can be programmatically determined and notification of changes to these is available to user agents, including assistive technologies. </old> <new> 1.3.1 Information and relationships conveyed through presentation are provided using technology specific accessibility techniques and notification of changes to these is available to user agents, including assistive technologies. </new> <old> 1.3.3 When the sequence of the content affects its meaning, that sequence can be programmatically determined. </old> <new> 1.3.3 When the sequence of the content affects its meaning, that sequence is provided using technology specific accessibility techniques. </new> This is the first 2 success criteria. The language may need reworking for each SC. It is difficult to make a sweeping replacement, each SC must be reworded. The definition also needs to be eliminated.

These technologies each have (or should have) specific accessibility techniques, features, and requirements. The content creator can only follow the requirements and techniques of the baseline technology. The author can only assume/hope that the UA will render the content accessibly. It is up to the UA to programmatically determine what to do with the content; or to parse the author supplied content unambiguously. will discuss more on the call. 1. ACTION: CL to find problematic instances of "programmatically determined" or other user agent assumptions [recorded in http://www.w3.org/2006/05/11-ua-minutes.html#action01] 2. ACTION: JA to Help CL to do formulate re-phrasing. [recorded in http://www.w3.org/2006/05/11-ua-minutes.html#action02]
