Comment (including rationale for proposed change):

Guideline 4.1 is concerned with ensuring compatibility with current and future user agents including assistive technologies. However, within WCAG 2.0 there does not appear to be any requirement to avoid the use of deprecated W3C technologies. Also there is no explicit indication that layout tables should not use structural markup for the purpose of visual formatting. It appears that many of the issues relating to the use of tables are intended to be covered by SC 1.3.1, however the HTML techniques relating to this SC in the \"Understanding WCAG 2.0\" document make no reference to the inappropriate use of table markup.

Proposed Change:

I suggest Guideline 4.1 contain a Level 1 Success Criteria which reads, \"When a table is used for layout, it does not use structural markup for the purpose of visual formatting.\"

I suggest Guideline 4.1 contain a Level 2 Success Criteria which reads, \"Deprecated features of W3C technologies are not used.\"

WG Notes: [TEAMA] Submitted by Team A 5/23/06 Put on hold, 5/25/06 telecomm {Partial Accept} The Working Group agrees that this should be a Failure. However 1.3.1 is the proper place for this and this is covered by two HTML failures under 1.3.1 titled "Failure of SC 1.3.1 due to using th elements, caption elements, or non-empty summary attributes in layout tables" and "Failure of SC 1.3.1 due to using structural markup in a way that does not represent relationships in the content". RE Deprecated W3C technologies: [The Working Group assumes this refers to deprecated features rather than deprecated technologies.] Not all deprecated features are accessibility issues or problems for AT. A blanket prohibition is therefore not felt to be appropriate. Are there particular deprecated features that you know to be a problem for AT that are not covered elsewhere in the guidelines." 5/25/06 WG Teleconf Call http://www.w3.org/2006/05/25-wai-wcag-minutes.html PUT ON HOLD Survey comments: http://www.w3.org/2002/09/wbs/35422/TEAMaMAY25/results#xLC565 Discussed in the 08 February 2007 telecon: Resolution: close 565 as ammended http://www.w3.org/WAI/GL/2007/02/08-wai-wcag-minutes.html {Partial Accept}

Resolution: The Working Group agrees that misuse of layout tables should be a failure. However 1.3.1 is the proper place for this and this is covered by two HTML failures under 1.3.1 titled "Failure of SC 1.3.1 due to using th elements, caption elements, or non-empty summary attributes in layout tables" and "Failure of SC 1.3.1 due to using structural markup in a way that does not represent relationships in the content". RE Deprecated W3C technologies: [The Working Group assumes this refers to deprecated features rather than deprecated technologies.] Not all deprecated features are accessibility issues or problems for assistive technologies. A blanket prohibition is therefore not felt to be appropriate. If we receive information about any such issues that we don't already know about, we will create failure techniques for them."
