[8] > http://dev.w3.org/html5/decision-policy/decision-policy.html The W3C process talks in terms of strong and weak, and in terms of objections. Weak is meant to be taken as the opposite of strong, and argument for is meant to be taken as the opposite of objection against. The existence of these guidelines (standards, laws, etc). that you and others cited is a valid argument. To my knowledge, no one is contesting that these guidelines exist. Some have argued that these have had little impact. None of the proposals or objections clearly established that these guidelines had an impact. Just so that it is absolutely clear: there is no assertion made that the guidelines did not have an impact. The only assertion that is being made is that there was an issue, we called for proposals and received three, there was an extensive period of discussion, and a call for objections. During the course of the above, it was brought to light that there are relevant guidelines, standards, laws, etc.; a question was raised as to whether such guidelines had an impact; and no clear and compelling response was produced during the course of the discuss > We could and probably should file a decision policy bug on that but I > suspect it would be marked WONTFIX.

We will discuss amongst ourselves and confer with members of the W3C Team on this as necessary. However, we do not think it is appropriate to formalize this in a written policy." So we can, and will recuse ourselves as necessary. In this specific case, while Maciej did provide feedback (but not due to the 2007 IRC log you mentioned, but because he actually participated by producing one of the proposals, one that the TF supported). I took the initial lead in evaluating this issue. Maciej's feedback improved the quality of the response, but did not materially change the decision. > Another bug on the policy regarding consistency was marked WONTFIX. > http://www.w3.org/Bugs/Public/show_bug.cgi?id=9894#c3 It is not clear how that is relevant here, but again: "The chairs discussed this issue. We believe that it is not the role of the chairs to enforce consistency as the highest value. Rather, it is our role to evaluate arguments made by members of the Working Group to determine which proposal draws the weakest objections. Thus, if particular Working Group members feel that consistency is important and believe that a given proposal would violate it, they should cite the consistency problem and explain their reasoning, either in another Change Proposal or in a straw poll objection." Again: consistency is clearly a good thing. But the responsibility to produce a consistent document is on the members of the working group. > The last available recourse for this particular issue at this point > would be to accept the decision; supply new information to the chairs > or escalate to a Formal Objection [9]. Correct. > The Chairs' decision directly countermands a task force recommendation: > > "RESOLUTION: While the HTML-A11Y Task Force prefers the proposal that > restores longdesc without warning we are prepared to accept the > alternative proposal...to produce a warning (assuming we can agree to > warning text)..." [10] > > Nowhere did the task force resolve to drop longdesc from HTML5. Countermands is a strong word. Prefers... not so strong. In any case, from the task force description: http://www.w3.org/WAI/PF/html-task-force "The Task Force does not, however, represent consensus of either of those Working Groups. All output of the Task Force should be considered as proposals, subject to vetting and modification by the WG receiving the proposal." > The task force should make a decision on how to the situation where > the HTMLWG Chairs' disregard this task force's collective judgment and > resolutions, as I suspect it may not be the last case. In the short term, a better use of those energies would be towards identifying new information (I hear that there is some from Oracle?) or on a Formal Objection. If there is to be a Formal Objection, I am quite prepared to actively participate in the process. My interest in this matter is not in any particular outcome. My interest is in getting this matter behind us. In the long term, a better use of those energies would be directed towards producing more complete proposals. Note that the following proposal makes no mention of standards, guidelines, etc: http://www.w3.org/html/wg/wiki/ChangeProposals/longdesc > Best Regards, > Laura - Sam Ruby > [1] http://www.w3.org/2002/09/wbs/40318/issue-30-objection-poll/results#xkeepnew > [2] http://www.w3.org/TR/2008/WD-WCAG20-TECHS-20080430/H45.html > [3] http://www.section508.gov/index.cfm?FuseAction=content&ID=12#Web > [4] http://www.usps.com/cpim/ftp/hand/as508a/508a_c6.html#508hdr13 > [5] http://cap.umn.edu/ait/web/TablesAndCharts.html > [6] http://www.webrichtlijnen.nl/besluit/tekst-besluit-en-toelichting/ > [7] http://lists.w3.org/Archives/Public/public-html/2010Aug/att-0112/issue-30-decision.html > [8] > http://dev.w3.org/html5/decision-policy/decision-policy.html > [9] http://www.w3.org/2005/10/Process-20051014/policies#WGArchiveMinorityViews > [10] http://lists.w3.org/Archives/Public/public-html-a11y/2010Apr/0180.html > > > On 8/12/10, Aurelien Levy<aurelien.levy@free.fr> wrote: >> I totaly agree with John and his will to create a formal objection. >> >> For the "External reference" point I can at least provide one example of >> accessibility government guidelines based on WCAG 2.0 and requiring longdesc >> attribut for complete description of complex images. >> It's the test : "4.9.
