16:16:13 TF proposal from TPAC: http://www.w3.org/html/wg/wiki/ChangeProposals/purely_decorative_images
16:16:14 SF: There is a response from me because the riginal bug was filed against the alt text document, that required a change proposal.
16:16:49 SF: The chairs wanted to widen the scope, so the same message was given across the spec and the alt text document.

16:17:58 HTML WG ACTION 195 (propose replacement text) http://www.w3.org/html/wg/tracker/actions/195
16:18:05 SF: There is an example of using an img of the Lady of Shallot. The page contains the poem of the same name. The spec suggests the image is therefore decorative, but the alt text doc says otherwise because it adds to the thematic information.
16:18:59 SF: It shouldn't be mandidated that you can't provide an alternative text.
16:19:28 RS: You have short names and long descriptions. There are different vehicles for providing the short.

16:22:20 JS: To keep this in context, two years ago when we came up with our consensus guidance we said there should be supporting documentation and that it should coe rom WAI.
16:22:31 -FtF
16:23:02 JB: Within the WAI co-ordination group, we spoke about getting this moved to the WCAG WG. BTW, there is also work being started on this by an external organisation that may result in confusion.
16:23:54 q+ to say that my change proposal points to WCAG and SteveF's alt techs document for discussion of purely decorative images after stating that should be controlled by CSS
16:23:59 q?
16:24:08 +??P1
16:24:39 SF: The alt text document was developed to counter the normative advice given within the spec.
16:24:44 GJR replacement text paragraph 1: "If an image is decorative but isn't especially page-specific -- for example, an image that forms part of a site-wide design scheme -- the image should be specified in the site's or document's CSS, not in the markup of the document."

16:25:03 GJR replacement text paragraph 2: "Exceptions to this rule, in cases where CSS cannot be used to display an entirely decorative image, are covered by the HTML5: Techniques for providing useful text alternatives. [HTML ALT TECHS] Authors are also encouraged to consult the Web Content Accessibility Guidelines 2.0 for more detailed information and acceptable techniques. [WCAG 2.0] "
16:25:15 SF: If we move the alt text doc out to WCAG, we need a pointer within the HTML5 spec.
16:25:32 steve, that is what my CP provides
16:26:33 present: John_Foliot, Silvia_Pfeiffer, Mike_Smith, Rich_Schwerdtfeger, Masatomo_Kobayashi, Janina_Sajka, Denis_Boudreau, Léonie_Watson, Steve_Faulkner, Eric_Carlson, Cynthia_Shelly, Michael_Cooper, Joshue_O'Connor, Frank_Olivier, Judy_Brewer, Sean_Hayes, Gregory_Rosmaita
16:26:50 SF: The main issue I'm concerned about, is that the advice in the HTML5 spec is not authoratative.
16:26:56 HTML5 should point to WCAG as per my change proposal
16:27:12 http://www.w3.org/html/wg/wiki/ChangeProposals/purely_decorative_images
16:27:15 SF: Text alternatives are for more than people with disabilities.
16:27:33 JF: It's not who benefits, but where the guidance comes from.
16:27:49 SF: I would be more than happy if the guidance was maintained outside of the HTML5 spec.
16:28:19 RS: When you put alt="" the spec should advice what the UA does with it.
16:28:20 I agree with you Greg. There should be a direct link from the spec to WCAG
16:29:05 SF: It' the normative authoring advice that needs looking at.
16:29:25 RS: If an image has role=presentation should the rendering be the same?
16:29:49 SF: Alt="" should be the same as role=presentation.
16:29:52 related: CP for definition of image (also agreed-to at TPAC 2010: http://www.w3.org/html/wg/wiki/ChangeProposals/first_2_paragraphs_of_definition_of_img
16:30:24 q?
16:30:32 my objection to role="presentation" was based on the fact that HTML5 lacked a role attribute -- now we have one, no?

16:30:41 oedipus, you wanted to say that my change proposal points to WCAG and SteveF's alt techs document for discussion of purely decorative images after stating that should be controlled

16:32:32 MS: Not sure what Laura's position on this actually is. It would be good if she could join the call.
16:32:41 GJR replacement text paragraph 1: "If an image is decorative but isn't especially page-specific -- for example, an image that forms part of a site-wide design scheme -- the image should be specified in the site's or document's CSS, not in the markup of the document."
16:32:49 GJR replacement text paragraph 2: "Exceptions to this rule, in cases where CSS cannot be used to display an entirely decorative image, are covered by the HTML5: Techniques for providing useful text alternatives.

16:33:07 We meaning them (sic) and us (sic)
16:33:54 MS: Perhaps we should postpone discussion on this until Laura is here.
16:34:15 JB: We probably souldn't hold up progress on this, as Laura may not be able to make it.

16:34:56 heh
16:35:02 JS: We previously voted GJR's proposal.
16:35:36 JS: Which leaves a second question of where this document/guidance lives.
16:35:49 correct -- we decided at TPAC what to say, and i was tasked to write it up as a ChangeProposal
16:35:53 q+ to ask if the content of the doc is ok, this is really just an issue of where the content lives, right?
16:35:59 SF: We were previously talking about role=presentation. James Craig says this isn't appropriate, as per the ARIA spec.
16:36:33 JC: Is this just about where this document lives?
16:36:37 -q
16:36:51 ack Joshue
16:37:00 CS: So the TF has a position on which position we go with?

16:38:09 JS: Is there anything else we need to say here on alt, before we move on?
16:38:21 yep
16:38:46 SF: We seem to be in agreement, but my one concern is that the change materials the chairs will be reviewing doesn't necessarily reflect the clarity we need.

16:39:47 SP: If someone has a decorative image, what's the recommended approach?
16:39:58 Stevef, what additions do you deem necessary to the change proposal for 122?
16:40:08 JF: It's a contextual answr, given in some detail in the spec.
16:40:28 GJR proposal says: if purely decorative, use CSS; if can't use CSS, consult WCAG 2.0
16:40:30 SF: If it's purely decorative, then give it a null alt.
16:41:12 if purely decorative, use CSS to embed image
16:41:18 http://www.w3.org/TR/wai-aria/roles#presentation
16:42:07 http://www.w3.org/TR/wai-aria/roles#presentation
16:42:20 if allow liberal use of will be offering an intollerable escape clause -- purely decorative images should be handled via CSS and only with role="presentation" in circumstances where CSS is not available
16:43:03 RS: role=presentation seems cleaner to me.
16:43:04 q+ to ask why aren't we saying use CSS to control purely decorative images?
16:43:17 JF: We'll need to keep alt="" for backwards compatibility.
16:43:32 CS: We'll need both for at least the next five years or so.
16:44:49 need to say for "redundant" images (such as a mailbox and the hypertext string "email us!" then the image can be role="presentation" or alt="" but that is the only compelling case for not using CSS for images (and even then, if an author is smart, he/she can do this with CSS anyway)
16:44:53 DB: Is there a risk to using role=presentation that we'll need to use role=information for images that are not decorative?
16:45:05 JS: It's presumed, so we probably wouldn't need to.
16:45:11 q?
16:45:30 CS: That was a point of contention at one point, but has since been settled.
16:46:12 SF: JC raised a question about alt="" and role=presentation. The spec says if a decorative image with role=presentation is encountered, remove it from the accessibility tree.
16:46:22 JS: What's the advice going forward?
16:46:27 q?
16:46:35 SF: That *is the advice, and we haven't questioned this so far.
16:46:37 ack oe
16:46:37 oedipus, you wanted to ask why aren't we saying use CSS to control purely decorative images?

16:46:52 GJR: Why are we saying use CSS to control purely decorative images?
16:47:18 GJR: We should say use CSS for decorative images full stop.
16:47:31 DB: You can't always do that.
16:48:02 janina, GJR replacement text paragraph 1: "If an image is decorative but isn't especially page-specific -- for example, an image that forms part of a site-wide design scheme -- the image should be specified in the site's or document's CSS, not in the markup of the document."
16:48:08 lwatson has joined #html-a11y
16:48:10 janina, GJR replacement text paragraph 2: "Exceptions to this rule, in cases where CSS cannot be used to display an entirely decorative image, are covered by the HTML5: Techniques for providing useful text alternatives. [HTML ALT TECHS] Authors are also encouraged to consult the Web Content Accessibility Guidelines 2.0 for more detailed information and acceptable techniques. [WCAG 2.0] "
16:48:10 MS: This is an issue for the change proposal itself, but with regards to the spec the change proposal is advocating for haing the spec reference some other txt/document.
16:48:35 MS: It's not an issue in terms of what we need to do for last call. The text we're referencing isn't the issue.
16:48:37 Greg, there are many situations in which you have no choice but to put your decorative image in the html. I don't think we can enforce that.
16:49:11 dboudreau, the second paragraph says, if you cannot use CSS, then consult Alt Techs and WCAG 2.0
16:49:24 JS: We're dicussing issue 80 ATM.
16:49:49 JS: We have guidance on 80, the question is whether we stand by this?
16:50:01 ack oedipus http://www.w3.org/html/wg/tracker/issues/80
16:50:01 JS: We were against using title, if alt wasn't provied
16:50:02 SF: Don't think there has been any disagreement on this, and we had a poll as well.
16:50:06 ISSUE-80 http://www.w3.org/html/wg/tracker/issues/80
16:50:07 oh, i see. But then, refering to techniques, we should find a reference to role="presentation" there if this is what we agree on
16:50:08 http://www.w3.org/html/wg/tracker/issues/80
16:50:28 dboudreau, yes, definitely --
16:50:45 MS: Issues 80 and 31 are waiting for the chairs.
16:50:57 JS: Do we need to revisit this?
16:51:13 which CP: http://www.w3.org/html/wg/wiki/ChangeProposals/ImgElement20091203 ??
16:51:16 CS: Our position has been stated, but issue 31 hasn't ben polled. Do we know what the TF position is?
16:51:48 SP: That label isn't a good substitute for alt?
16:52:18 MS: There are a buch of change proposals for issue 31.
16:52:31 SF: We decided to put forward option 3 (perhaps 2) on this.
16:52:48 MS: Laura wasn't in agreement with this. Would be good to have her input here on this.
16:53:05 SteveF, you are talking about http://www.w3.org/html/wg/wiki/ChangeProposals/ImgElement20091203 right?
16:53:21 SF: If we're in agreement that the normative advice should be taken out of the spec, our response to 31 should either include or encompass that.
16:53:44 MS: It's a different problem. We do need to have normative text in the spec. This is about the exceptions and what they are.
16:54:01 SF: What should the exception be if you don't have an alt attribute on an image?
16:54:19 MS: In terms of the conformance/validator, what should be an acceptable substitute?
16:55:26 hixie's change proposal for Issue 80 and Issue 31: http://lists.w3.org/Archives/Public/public-html/2010Jul/0050.html
16:55:35 SF: Summary is that it's ok to h have role=presentation, alt="", or a image with no alt and an associated figcaption, or aria-labelledby.
16:55:42 JF: Did we have agreement with that?
16:55:49 SF: Yes, I think we do.
16:56:26 JS: We've discussed this sevral times and have always arrived at the same place. We should mntion this in the survey.
16:57:01 -> http://www.w3.org/2010/11/04-html-wg-minutes HTML meeting in Lyon
16:57:43 RRSAgent, make minutes
16:57:43 I have made the request to generate http://www.w3.org/2011/03/19-html-a11y-minutes.html MikeSmith
16:58:40 SP: How does aria-labelledby and title fit into this?
16:59:10 SF: The consensus was that title shouldn't be considered a conforming image, as far as the provision of a text alternative goes.
16:59:27 DB: Is that because ATs don't support both?
16:59:41 CS: We feel it's the right way to do it.
17:00:41 SF: Historically, it hasn't been keyboard accessible - the information might be important. It's a browser limitation, but it's been known about for 10 years or more and there is no srong advice in the spec about providing a text dscription is a device independent way.
17:01:14 JF: When IE started putting tooltips in, the attribute values were often duplicated causing information to be doubled up with some ATs.
17:01:29 @title often contains useful metadata (file type, size, etc.)
17:01:57 CS: In the Lyon/TPAC minutes I can't find an agreement.
17:02:15 dboudreau, definitely need to push screen reader devs to support both alt and title (in JAWS, one can set cascade of attributes to expose)
17:03:09 but need to have a query for title and aria-label
17:03:15 another problem with @title is that it's a hover effect only (tooltip) therefore useless when using the keyboard only and on mobile
17:03:34 dboudreau, agreed
17:04:08 SF: ARIA has no effect on the UA rendering of stuff. So you display the content of aria-label means you're asking the UA to do something extra. I'm not opposed to that, but that's the reason whay it's not in the spec.
17:04:11 greg, if we were to push them towards supporting both attributes, then users wold get the info twice... pretty annoying don't you think?
17:04:56 CS: Alt is rendered as a place holder, aria-label isn't.
17:05:07 q+ to time check, we have 1/2 hour left allocated for this session unless we pre-empt another one; also need to hit longdesc
17:05:09 unless we could get mechanism that only reads the value of @title when it's different form the @alt's value... but then again, this is just another specific setting available in jaws
17:05:20 action Steven to send e-mail message to a11y TF mailing list with a draft summary of the TF consensus position on what exceptions should be allowed for alt-less images (e.g., role=presentation, aria-labeledby, etc.)
17:05:20 Sorry, couldn't find user - Steven
17:05:26 action Steve to send e-mail message to a11y TF mailing list with a draft summary of the TF consensus position on what exceptions should be allowed for alt-less images (e.g., role=presentation, aria-labeledby, etc.)
17:05:27 Created ACTION-111 - Send e-mail message to a11y TF mailing list with a draft summary of the TF consensus position on what exceptions should be allowed for alt-less images (e.g., role=presentation, aria-labeledby, etc.) [on Steve Faulkner - due 2011-03-26].
17:05:27 dboudreau, alt needs to be a functional equivalent of the image being described, title is a hint/advice -- when i use both i never use the same text -- validator should mark identical alt and title strings assigned to a single element as an ERROR and instruct the author to either use one or to change the value of one
17:06:00 validator should mark identical alt and title strings assigned to a single element as an ERROR and instruct the author to either use one or to change the value of one
17:06:07 SP: So I'm supposed to use alt as an author, and ignore the rest?
17:06:22 CS: No, they're different things for different situations.
17:06:43 greg » i like that idea very much. from a validation perspective this is good, but most authors won't validate therefore won't be stopped by this
17:07:00 q-
17:07:14 RS: When you write the overview, could you include somethig about using aria-label?
17:07:15 so while i do like it, i don't think it will be useful or helpful enough for the end user
17:07:53 dboudreau, so ATAG needs to say "if author enters identical value for @alt and @title, generate an error message and query for different strings (alt for equivalent info, title for extra metadata)
17:08:29 Topic: Longdesc
17:08:40 http://www.w3.org/WAI/PF/HTML/wiki/Verbose_desc_reqs
17:08:49 greg, i fail to see how this would prevent authors from abusing both attributes with the same value
17:08:49 JS: There are two questions... Where and what. Let's take them in reverse order.
17:08:56 http://www.w3.org/WAI/PF/HTML/wiki/Verbose_desc_reqs#Satisfying_These_Requirements_for_HTML5
17:09:08 JS: I suspect there is consensus within the TF to get longdesc back in the spec.
17:09:15 laura's longdesc research: http://www.d.umn.edu/~lcarlson/research/ld.html
17:10:14 JF: We've heard from lots of people that there needs to be a visual indicator of longdesc, for sighted people who would benefit. Longdesc was originally intended to be hidden. Browsers seem reluctant to do this.
17:10:17 dboudreau, if author using authoring tool, that tool should know to watch for and flag as error identical values for @alt and @title -- sure won't help hand-coders like myself, but we seem to be a dying breed
17:10:29 q?
17:11:00 dboudreau, either that or threaten the author with "cruel and unusal punishment"
17:11:18 JF: Several browser vendors have epressed an interest in creating a visual indicator plugin of some kind.

17:11:37 tools that support LONGDESC: http://www.d.umn.edu/~lcarlson/research/ld.html#tools
17:11:51 you may be right... but i'd be reluctant to suport this knowing it would end up meaning redundancy for end users.. i'd rather go with the threat and personnaly dliver it myself (if we have the budget)

17:12:33 dboudreau, my idea would only work with additions to WCAG, ATAG and UAAG (expose all metadata)
17:12:44 JF: If the browsers themselves can't close the loop, perhaps ATs will
