done

<janina> Ah, let's clear and try that again!
preview agenda with items from two minutes

<scribe> ScribeNick: ShaneM

ShaneM - we are working on a draft extension spec around note / noteref.
Some report at next A11Y task force meeting.

Cyns: Are there any plans for meetings at CSun?

janina: There was some talk of WCAG meeting but didn't get put together. So
I don't think so.

Cyns: I thought john mentioned meeting at CSun a few weeks ago.

Leonie: Web Platform considered doing some A11Y stuff, but it was cost
prohibitive.

janina: That is frequently the problem with meeting at CSun

JF: That is also when the AC reps are meeting in Boston. So that will
impact many people who might have participated.

Cyns: The sunday after CSun is Easter this year, so that will impact a lot
of people too.

Gottfried: I wasn't on the mailing list but now I am (and in the group).
... there is a new working group in Active and Healthing Ageing. I am
leading the effort. We are trying to promote personalized user interfaces.
Make the case that different people need different user interfaces. This
has a lot to do with a11y.
... we wills start with a number of user profiles to show how different
types of people need to interact with different environments.

janina: is there a URI?

Gottfried: not yet. If anyone wants to be involved let me know.

Ryladog_: I am interested.

<Gottfried> Related to the last topic: URL for the EIP-AHA Action C2 in
which the new work on Personal User Experience is starting:

JF: Fred delivered on ACTION-2009

ACTION-2009

<trackbot> ACTION-2009 -- Fred Esch to Review media capture depth stream

PENDINGREVIEW

<trackbot> http://www.w3.org/WAI/APA/track/actions/2009

fesch: no A11Y concerns with this document at this time.
... the tech has a lot of potential for a11y. I put a note in the action.

ACTION-2009: close

<trackbot> Sorry, but I think you meant to close ACTION-2009.

<jf> ACTION-2007

<trackbot> ACTION-2007 -- Fred Esch to Review shacl use cases and
requirementshttps://www.w3.org/tr/shacl-ucr/ -- due 2016-02-10 --

close ACTION-2009

<trackbot> Closed ACTION-2009.

fesch: no concerns - really low level stuff.

close ACTION-2007

<trackbot> Closed ACTION-2007.

ACTION-2006

<trackbot> ACTION-2006 -- John Foliot to Draft comment to ensure authoring
guidance is provide on emehttps://www.w3.org/tr/encrypted-media/ -- due
2016-02-10 -- OPEN

<trackbot> http://www.w3.org/WAI/APA/track/actions/2006

JF: need another couple of days.

ACTION-2005

<trackbot> ACTION-2005 -- Fred Esch to Review media queries level 4
https://www.w3.org/tr/mediaqueries-4/ -- due 2016-02-10 -- PENDINGREVIEW

<trackbot> http://www.w3.org/WAI/APA/track/actions/2005

fesch: we definitely have an interest in this. Particularly a high contrast
MQ.
... It is also of interest to DPub.
... MS has proposed a high contrast MQ but it is not noted in the document.
... pointer may have several MQs for features like hover, light-level. We
might want setters for them so that we could override for some users.
... there are syntax diagrams in there - the SVG a11y task force will
provide feedback on the SVG in the document. That will be done
asynchronously.

Cyns: Wasn't there an email about high contrast a few weeks ago? If there
was, we (MS) are interested in doing that.

fesch: Actually there is an action from 2012 about a high contrast MQ.

janina: in the indie-ui working group there were requirements for user
personalization. We thought that might be MQs but there is some pushback
from that.
... Dpub has some dialog about that.
... ShaneM it looked like you had a great suggestion for generalizing the
opportunity and asking CSS for a specific suggestion and we could deal with
the general case later.
... personalization is part of the ARIA activity. Rich is interested in
pushing it once 1.1 is shipped.
... From APA perspective, we need to continue to push to get this done. We
should let them know that we have a lot of interest in the development and
note there is a lot of need for generalized P10N opportunities.

fesch: Florian did note that there is some interest in P10N in an email.

<fesch> There are some areas where preference media queries may have a role
to play, and the CSSWG is interested in looking into these even though they
have not been prioritized so far. This would be focused on accessibility,
tying into the OS level controls that already exist. Examples put forward
by apple have included: preferring reduced animation, preferring using
shapes rather than colors to...

<fesch> ...draw distinctions between things, or preferring reduced
transparency.

<fesch> The difficulty is that these things need to be fairly abstract (if
they were not, user style sheets would be more appropriate), yet
actionable, and at the same time be a sufficiently short list that
implementors and authors can be expected to care. The most likely path
forward here is to work from the list of settings that pre-exist in
operating systems and standardize that.

fesch: he is suggesting that they work on what the native platforms have in
common at a low level.
... what we really need is someone to put forward all of the ideas we want
- not just what is already supported universally.

Cyns: It would be good if someone from Apple would participate. Their
colors stuff is really different.

janina: James Craig is active in this area.

fesch: we need to note on the wiki that we have a huge interest in this
spec.

<scribe> *ACTION:* MichaelC to update the wiki to add note about our
interest in MQ4 [recorded in
http://www.w3.org/2016/02/10-apa-minutes.html#action01]

<trackbot> Created ACTION-2010 - Update the wiki to add note about our
interest in mq4 [on Michael Cooper - due 2016-02-17].

janina: florian pushed back on using a MQ for deciding if a user wants to
see details or not. There was some comment from James Craig this morning
(on the dpub mailing list).

jf: there is a definitely tie in to the cognitive task force.
... is anyone from that task force aware of these discussions.

janina: I don't know if they need to be in CSS right now - they are pretty
loaded already.
... not sure who on the team outside of Lisa is a technology person and
could assist with spec development.

ShaneM: why can't they pick one thing and do it (via MQs)? We do all sorts
of things that are one off.

CSS Fragmentation Model level 3

Looks like we are up to date.
CSS Flexbox Issues Status -- Matt, Fred, Janina

janina: Matt, can you bring us up to speed after Sapporo? We will do a
detailed dive on the 24th.
... fantasai will provide some input by the 24th as well (hopefully)

mck: most of the people on the call were in Japan.
... most of the discussion there was about whether the Firefox behavior
that changes keyboard focus according to flexbox instead of the DOM.
... there was a bug filed on FIrefox. CSS seemed to agree it was a bug.
APA/ARIA seemed to be divided on whether it as bug.
... at the conclusion I thought APA agreed to not take a position
(therefore leave it interpreted as a bug).
... there were lines drawn in Japan with poeple having different
viewpoints. We did a little mockup in Japan. I was unable to dig that code
up again.
... it was a test to see whether the AX tree and the reading order was also
being adjusted, or whether the visual order was out of sync with the
reading order.
... at least one case it was out of sync.

janina: that sounds like a good review.

<LJWatson> 6My 2p on the subject of flexbox
http://tink.uk/flexbox-the-keyboard-navigation-disconnect/

janina: I know that Rich had a lot of concerns with the flexbox spec when
it moved to CR. There was a concern from IBM.
... the APA group should still say something. CSS said that they would put
forward a position. I don't think that we need to block CR. We would need
to block PR if there is no conclusion about this issue.
... we are still expecting that writeup from fantasai and hopefully that
will resolve the position about reading order etc.
... Perhaps there will be bugs against browsers, but hopeful that it will
get to a meaningful resolution.

mck: I think that it is important that we characterize the behavior of
Firefox. We found one case where the behavior was not as horrible as it
could have been.
... I think that the majority of people felt firefox shoudl revert the code
and not convert the reading order / visual order based upon flexbox
properties.

Cyns: I disagree. The visual and reading order need to match. There is an
impass that needs to get resolved.

mck: based upon the CSS spec it definitely is a bug.

Cyns: then the CSS spec needs to get fixed, because firefox is doing
something useful.

mck: janina, we need to decide if APA should take a position on this. I get
concerned that we might burn political capital for something where there is
an engineering solution.
... can anyone show where there is an engineering solution for this. The
burden of proof should be people bringing forward engineering problems that
cannot be resolved without the orders matching.

janina: We might be diving into things that should be discussed on the 24th.

Cyns: I agree that using concrete examples is a way to move forward.
... it may be that firefox solution is not the best one. But I want a
solution that does not limit innovation. This issue has been a problem for
as long as I have been doing this.
... and flexbox is a useful thing and we probnably don't want to block it.

janina: yes - we don't wnat to block it.

LJWatson: +1 to Cyns comments. We have had this problem for as long as
layout has been separated from content. The DOM does not get rewritten all
the time. We need to fix this at the browser level.

mck: IBM is considering a formal object if it puts the reading order and
the DOM out of sync.

Cyns: you mean if the browser is allowed to repair or not?

fesch: If your code fails a test because of the spec, then that is
unacceptable to us.

Cyns: what if the spec allowed innovation?

janina: I don't think fesch is ready to talk to that. It is on the table.
We need to come up with an approach that preserves the ability to innovate
and also preserves good readong order that is reasonable.
... we need to see the language, have the conversation, and see the tests.

fesch: Do they need two implementations?

Cyns: If it is a SHOULD, then no.

LJWatson: If it is not done in the DOM then there are a lot of techniques
available that cannot do the job.

Cyns: Blocking flexbox will not stop the other things in CSS that already
have this problem.
... we already have the issue that the tab order, the screen reader order,
and the visual order don't match in various situations.

<LJWatson> +1 to cyns again.

mck: The nice thing about flexbox is that you can reorder visuals without
effecting the desired reading order / keyboard order.
... flexbox gives us a lot of flexibility in solving our reading order
problems.
... LJWatson you mentioned drag and drop. I have talked about that problem
to engineers and none of them have thought that CSS is the right way to
solve it instead of reordering the DOM to get the visual order correct.

LJWatson: But most engineers dont want to do that because it is not
performant. Rewriting the DOM is expensive.

Cyns: That's one of the goals of flexbox - that we can avoid those costs.

mck: I am not sure that is really the motivation.

LJWatson: How much evidence do we need that separation does not work?
