WAI-UA F2F Day 1 -- 20 Oct 2008

<KFord> Oh, well good morning/evening to you all.

<KFord> Sympathies to anyone who was a Red Sox fan since some are from Boston.

<KFord> If I'm the only one phoning in, don't let me block progress.

<Jan> yest it's 8224

<KFord> zakim +1425883-3343 is kford

<KFord> Scribe: KFord

<jallan> This morning we will be reviewing the Sept 25 editor's draft http://www.w3.org/WAI/UA/2008/WD-UAAG20-20080925/WD-UAAG20-20080925.html

<jeanne> The agenda is at http://www.w3.org/WAI/UA/2008/10f2f

Jallan: Goes over meeting highlights for the day.
... We welcome your feedback since you are coming from a newperspective, we always welcome input.

Jeanne: We talked about some organization at dinner. Let's bring folks up to date from our dinner conversations.

sounds good to all.

JAN: goes over existing five principles.

Jim: do those ever conflict?

JAN: The hardest split is between perceive and operate. Let's say you want to operate a button, where do you draw the line between perceive and operate.

JAllan: expands on this and gives example of web applications with a UI inside a UI and so forth.

JAM: We might benefit from being more general like ATAG.

JAN: ATAG has two main points in item 1. Web sections of an authoring tool must follow ATAG. 1.2 non-web based follow software standards for operating system and such.

kford See ATAG guidelines for exact wording.

Jeanne: This isn't really about how accessible but more about operating system conventions.

JAllan: I don't know that you can separate things.

Jim: If you don't honor the operating system conventions you'll have to create your own.

JAN: OS conventions often apply only to the chrome. Web content you sometimes have more freedom.

JAllan: in the old version trying to use a strategy that separated content from chrome, we ended up duplicating a lot.

JBrewer: Abstract seemed to make sense. Status needs an update.
... Introduction needs some work.
... The other issues section seemed random.
... We don't spend any time orienting people to the document i.e. what are principles, criteria and guidelines and such.
... The format itself also lost me a bit. Level labels are all bold. They shouldn't be so the success criteria stand out more.

kford: mentioned three points I raised on list about abstract and intro.

JAllan: Reads kford's points.
... Why talk about braille printing as an example, strengthen for access.

1. Abstract presently mentions it is important to communicate with assistive technology. Should we mention that it is important to support accessibility APIs where they exist in the intro as well?

2. What's the point of the following sentence in the abstract

Technologies not addressed directly by this document (e.g., technologies for Braille rendering) will be essential to ensuring Web access for some users with disabilities.

I think of a Braille display much like a monitor. It is the job of the assistive technology in the case of the Braille display to determine what's displayed. This sentence just seems kind of out of place.

3. The abstract needs to be strengthened in terms of indicating how web content is important. Right now I'm left with the impression that this is more about user agent user interface.

JAllan: We had some discussions about the fact that there's a lot of screen readerness or AT built in in a subliminal way. Could we strip this out and be more generic about communicating with AT in general.
... Start with the total standard and if we need specifics, make them specific to a type of user agent.

JBrewer: Concerns me that this might be a reorg.

JAN: I don't think so, this would only be some changes.
... We could import from ATAG snce they have a lot of details on how to read the document.

JBrewer: More comments about intro and gaps.

Detailed walkthrough of intro

group looks at AU intro.

JBrewer: This is more of what I'd expect.

<jeanne> http://www.w3.org/WAI/AU/2008/WD-ATAG20-20080929/WD-ATAG20-20080929

Authoring Tool 2.0 http://www.w3.org/TR/ATAG20/

Jeanne: I was looking at WCAG also.

http://www.w3.org/TR/WCAG20/

Jeanne: I think we should be harmonizing with WCAG.

Organization of Introduction

group looks at existing intro

group talks about installation in intro.

JBrewer: What do we want to say about security? If they do we should get a checkpoint.

Jeanne: Gave example of password example.

JBrewer: Keep the first paragraph on security and ditch the second.

More discussion around security.

Group agrees to keep paragraph 1 under existing security and put it in some overall intro section.

Second paragrph under security to be deleted.

group now talking about user control.

group agrees to delete control of automatic brehavior section

group now discussing configurability.

<jeanne> I can get them

<jallan> issue: weave into conceptual intro - Teirs of configurability: wizard, menus, xml listing (firefox)

Group talks about some organizational aspects of tracking conversation.

<trackbot> Created ISSUE-8 - Weave into conceptual intro - Teirs of configurability: wizard, menus, xml listing (firefox) ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/8/edit .

JAN making edits on the fly.

Jeanne tracking actions.

JAllan keeping list of issues too.

JBrewer talks about creating an understanding document.

JBrewer wonders if we have the resources but thinks that developers would find it helpful.

group now talking about device independence.

JBrewer: Why is this here?

<jeanne> issue: Save Intro Configurability section for a potential Understanding document

<trackbot> Created ISSUE-9 - Save Intro Configurability section for a potential Understanding document ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/9/edit .

<scribe> ACTION: kford to draft general sentence about device independence for intro. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action01]

<trackbot> Sorry, couldn't find user - kford

<jeanne> ACTION: KF to draft a general sentence to summarize the Independence section to be included in the conceptual overview. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action02]

<trackbot> Created ACTION-34 - Draft a general sentence to summarize the Independence section to be included in the conceptual overview. [on Kelly Ford - due 2008-10-27].

group now talking about additional benefits.

JBrewer thinks this should be deleted. Probably need a companion document but should get Education and outreach to write this.

<jeanne> ACTION: JB to discuss with Shawn and EO to draft a Benefits of UAAG [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action03]

JBrewer: We just finished intro walk trhough.

Group revisiting beginning discussion to capture specific items.

Talking about which software guidelines we want to reference when we talk about other guidelines.

More talk about intro.

JBrewer: use as much as possible the intro from WCAG.
... Look at ATAG.

The group is on break just now.

http://www.w3.org/WAI/UA/2008/10f2f

group talking about status and process.

Definition of User Agent

Group changing from agenda slightly. Will move through the document and review section by section.

JAN presenting different definitions of user agent.

kford raised concern that we have two definitions.

See various W3C documents for definitions presented by JAN.

kford discussion on what is a user agent.

JBrewer: In WAI we want to ensure our definitions are comprehensive enough to cover anything that could be used on the web.
... Is there anyone who wants to keep the two definitions of user agents?

<jeanne> ACTION: JA to draft a new proposal foro the definition of User Agent that is in harmony with WCAG and ATAG as well as review HTML5 definition of browser. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action04]

<trackbot> Created ACTION-36 - Draft a new proposal foro the definition of User Agent that is in harmony with WCAG and ATAG as well as review HTML5 definition of browser. [on Jim Allan - due 2008-10-27].

Principle 1

PRINCIPLE 1. Follow applicable specifications and conventions

<jeanne> change "Observe" to "Comply with"

discussion about environment versus system.

kford looking at which W3C docs have rational and wich don't.

<scribe> Scribe: Jeanne

discussion of the need for a rationale. AtAg has a rationale, WCAG doesn't, but WCAG has a separate Understanding document.

JA: I would rather see a clear statement that doesn't require a separate rationale.

<jallan> issue: do we need a rationale layer at the guideline (or any level)

<trackbot> Created ISSUE-11 - Do we need a rationale layer at the guideline (or any level) ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/11/edit .

JB: Principle 1: Change "Follow" to "Comply with"

Discussion of changing organization of Guidelines to web-based and non-web based to harmonize with ATAG and simplify the Success Criteria of Principle 1.

Examples of web-based user agents would be an email client (e.g. gmail) that is a web based user agent for email. YouTube video player would be a web based user agent.

JR: Web based user agents would be required to conform to WCAG. Non web based user agents would conform to the Operating environment

KF: it is important that developers document what the choices they make.
... It gives the developer more flexibility in case requirements are outdated.

<jallan> Jan's email compatability http://lists.w3.org/Archives/Public/w3c-wai-ua/2008OctDec/0014.html

Issue: Build into the Conformance statement that the developer needs to cite the operating environment features that support the conformance claim (e.g. using the OS audio controls)

<trackbot> Created ISSUE-12 - Build into the Conformance statement that the developer needs to cite the operating environment features that support the conformance claim (e.g. using the OS audio controls) ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/12/edit .

<jallan> jan's email testing http://lists.w3.org/Archives/Public/w3c-wai-ua/2008OctDec/0013.html

Success Criteria for 1.1

KF: concerns with the list of 1.1.1 -- we should have a common list that we apply to all criteria. Does the list stand the test of time?

JB: I share concern. Does this list reflect other areas of our document?

JimBell: Is Product Installation too vague. Does it include updates and software management?

JR: The ATAG wording requires accessibility conformance.

JA: Core operating system requirements, like dialog boxes are needed for Assistive Technology. You need to follow the OS.

JR: We need 1.2 and 1.3. I recommend replacing 1.1 with the ATAG wording of web-based and non-based.

http://lists.w3.org/Archives/Public/w3c-wai-ua/2008OctDec/0013.html

JS: Suggest splitting the web based and non web based at the Guideline klevel rather than the Principal level.

KF: Want to require the User Agent to state how they are compliant and what they are using to be compliant.

JA: Take Principal A from ATAG and change it to UUAG.

Lunch Break

<KFord> JAllan: Decision, we can continue on 1.1 or go back to the agenda and talk about accessible printing and video.

<KFord> JBrewer: We should at least finish cleanly on 1.1.

<KFord> JAN summarizing his edits for 1.1.

<Jan> http://www.w3.org/WAI/UA/2008/WD-UAAG20-20081020/WD-UAAG20-20081020.html

Principle 1 continued

<KFord> Group to spend 20 minutes on 1.2 and 1.3.

Jan has updated the document to add the new 1.1 Guidelines and deleted the former Guideline 1.1.

<KFord> Discussion around where ATAG principle 1 was pulled in. Is this replacing existing principle 1 or Guideline 1.1?

<KFord> More discussion around if the change becomes too narrow.

<KFord> now talking about 1.2 support accessibility features.

<jallan> KFord: focus on clarity. this is not clear

<jallan> Mark: +1

Proposes a bare minumum: The user agent implements the features of the technology that support multiple modalities

<jallan> device independence

<jallan> alternative content

<jallan> explict associations

<jallan> structure (headings, list, etc. - not div and span)

<jallan> support assistive technology

<jallan> known/published accessibility features

JB: we want to identify and articulate core principles of accessibility, multi-modal principle is good for that but may not be broad enough

issue: A list of the core principles of the essential accessibility features

<trackbot> Created ISSUE-13 - A list of the core principles of the essential accessibility features ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/13/edit .

<KFord> Loads of discussion about accessibility features.

<KFord> And where definitions come from and what should be in UA.

<KFord> Discussion was around guideline 1.2.

<KFord> JAllan read old 1.0 guideline.

Implement the accessibility features of a specification that are identified as such in the specification or as necessary to satisfy a requirement of WCAG

Implement and cite in the conformance claim the accessibility featuers of a specification that are identified as such in the specification or as necessary to satisfy a requirement of WCAG

issue: Include in the conformance claim

<trackbot> Created ISSUE-14 - Include in the conformance claim ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/14/edit .

<KFord> Group now talking about rendering content.

<KFord> kford Discussion around what content was being talked about. Was this all content or supported content?

<scribe> scribe:kFord

Consensus was this was supported content.

JR: Let's think about this. Gave example of how a table linearizer would break this guideline.

<jallan> from UAAG 1.0 http://www.w3.org/TR/UAAG10/guidelines.html#gl-content-access

<jeanne> ACTION: JA to take the old text from UAAG 1.0 to rephrase Guideline 1.4 [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action05]

<trackbot> Created ACTION-37 - Take the old text from UAAG 1.0 to rephrase Guideline 1.4 [on Jim Allan - due 2008-10-27].

guideline on unhandled content moving to level a.

JBrewer: Revisiting discussion around bolded text.

Group looks at WCAG.

<jeanne> resolved: Move 1.4.2 (former 1.3.2) to Level A (Consensus reached)\

JBrewer: No need to list all the no criteria at level x for this item with this change.

<jeanne> ACTION: JR to reformat the success criteria so that the level designation follows the SC in parentheses following the example of WCAG. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action06]

<trackbot> Created ACTION-38 - Reformat the success criteria so that the level designation follows the SC in parentheses following the example of WCAG. [on Jan Richards - due 2008-10-27].

JAllan: Are we happy to move away from principle 1?

group decides to end.

End discussion of principle 1.

<jeanne> SAZ: Recommend that you use the mapping to the User Needs Analysis.

<shadi> http://www.jtc1access.org/documents/swga_290_PDTR%20Part%201%20User%20Needs%20Summary.zip

<jeanne> ACTION: JS to look at the User Needs Analysis document and ensure that we have all the success criteria necessary for UAAG. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action07]

Printing from user agent

<jallan> Printing in a user agent

<jallan> * open proposal for new success criteria

<jallan> (http://lists.w3.org/Archives/Public/w3c-wai-ua/2008AprJun/0072.html)

<jallan> * Definition of Flow

<jallan> (http://lists.w3.org/Archives/Public/w3c-wai-ua/2008AprJun/0117.html)

Jallan: When you print from the user agent, the user agent doesn't reflow, you get the right margin cut off.

JBrewer: Remind me why this is an accessibility issue.

JAllan: You could enlarge on the screen and not get what you printed in any relationship to the screen.

<jallan> scribe: Jim

<jallan> all: agree that printing is an accessibility issue

<jallan> JR: reviews the proposal.

<jallan> KF: want to print with the user display changes honored

<jallan> JA: printing sometimes fails with no user changes, even though it renders fine

<jallan> JS: that is a repair issue. depends on the author coding.

<jallan> MH: change print dialog to allow options, print standard, print while honoring user screen changes

<jallan> ... does UA need to provide this dialog?

<jallan> ... e.g. Opera has separate printing dialog

<Jan> JA: We've agreed printing is access issue

<Jan> JA: We need to craft success criteria

<jallan> proposal: Print Scale: If a print from viewport feature is provided,

<jallan> the user has the option of printing using the viewport's scale settings

<jallan> such that the user agent should attempt to *passively reflow* the

<jallan> content into the horizontal dimensions of paper. If passive reflow is

<jallan> not possible, more than one sheet of paper will be required horizontally.

<jeanne> scribenick:jallan

definition: *Flow*

The process that fits a stream of text or content blocks into lines in

a two-dimensional visual display. The flow is dictated by the primary

reading direction, the fixed dimension of the display, and the

position of the next line. For example, most Latin-based documents use

a horizontal left-to-right text layout flow in which the display width

is fixed and the next line appears below the previous one. A *reflow*

occurs when changes to the content or the display dimensions

necessitate recalculating this layout. If the display dimensions are

tied to the viewport dimensions, when the user changes the viewport

size a reflow will occur.

1. In *passive (re)flow*, the user agent inserts soft returns as

needed to keep the content blocks within the fixed display dimension,

but does not attempt to rescale or split oversize blocks. This may

result in content blocks overflowing the fixed display dimension.

2. In *active (re)flow", the user agent inserts soft returns as needed

to keep the content blocks within the fixed isplay dimension and also

attempts to rescale or split content blocks to prevent overflow.

JS: having something ugly better than losing information

JB: how to tersify
... to prescriptive. how to generalize, so we know what we want to achieve.
... problem to solve: printing without losing information.

KF: also, want user to be able to customize the size at which information is printed

<jeanne> propose: Print Preserves Font Sizes: When a print option is available, the user has the ability to customize the size that is printed. in the printed output

<jeanne> Print Preserves Font Sizes: When a print option is available, the user has the ability to customize the font size that is printed.

JA: also need to honor the print style sheet (that removes navigation, adverts, etc.)

JB: this is not in the JTC1 user requirements for folks with cognitive issues

KF: must say, ok to follow author's print css, but must not lose and 'real' content

<jeanne> ACTION: JS to follow up with WCAG group that we recommend a technique where a print stylesheet is created that eliminates the navigation and extraneous parts of the page so that cognitive-disability users have an easy way to print only content. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action08]

<trackbot> Created ACTION-40 - Follow up with WCAG group that we recommend a technique where a print stylesheet is created that eliminates the navigation and extraneous parts of the page so that cognitive-disability users have an easy way to print only content. [on Jeanne Spellman - due 2008-10-27].

JA: 3 points--do not lose information, honor author print css, scale font size of print

<Jan> The user had the ability to customize the size at which information is printed.

<Jan> Information should never be lost during printing

<Jan> Print Preserves Font Sizes:

<Jan> - When a print option is available, the user has the ability to customize the size that is printed in the printed output

<Jan> - nothing is lost

<Jan> - limit to one dimension of pages (so one column running down for English)

<andrew> for the meteorologically curious on the phone - http://riviera.angloinfo.com/weather/

<Jan> - honour author's print stylesheet

<Jan> Technique ideas

<Jan> - provide a "print" view that applies the printer style sheet - actually this might be a cognitive technique

<jeanne> ACTION: MH to draft a proposal for printing including the 3 concepts --do not lose information, honor author print css, scale font size of print [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action09]

Video Requirements

Proposal from Mark http://lists.w3.org/Archives/Public/w3c-wai-ua/2008OctDec/att-0023/ua-video.txt

JS requests that Mark summarize what he wanted to accomplish.

<Jan> JS: What's diff between player behaviour and media controls?

MH: What are the areas I need to have access to: controls, properties, alternative content and player behavior.
... the player behavior is not the controls or properties, but the bridge between the controls and the alternative content.
... is it ok to scatter the control issues thoughtout the guidelines, or should we concentrate the video section?

JS: If we don't concentrate it, then companies that make video will have to search the entire document and may miss them. We have a special section for Keyboard under Operable.

AA: These are not casual users for this document. Software developers who have video as a portion of the product will find it discontinuous.

<jallan> JA: sortable view - a, aa, aaa, vidow, keyboard, timebased media

<jallan> JA: what is a video... .mov, animated gif, flash, svg application

<jallan> JR: could use 'time-based media' instead of video like wcag does

<Jan> MH: In my email...

<Jan> MH: Reading point 1 in email....

<Jan> MH: Media controls...

<Jan> MH: In draft we talk about slowing but not speeding

<Jan> MH: Trying to see if I missed anything

<Jan> KF: We should have speedup right?

<Jan> MH: Yes

<Jan> KF: Good I think its essential

<Jan> MH: Pitch maintenance technology allows audio to follow sped up video

<Jan> JA: Let's go through Media controls

<Jan> MH: If we can scale text are we also scaling other parts of visuals.

<Jan> MH: Comment from another email was about adjusting contrast

<Jan> MH: And if we are changing contrast we need to be able to reset to defaults

<Jan> JA: Let's do "lay, Pause, Stop, Skip Forward/Back if media markers are

<Jan> present, fast forward/rewind, goto start (??end??), playback presentation rate

<Jan> adjustment (slower/faster/normal ?? rate change may be presets or incremental ??

<Jan> (related to 3.3.8). "

MH: these are the functions I pulled out for Media controls including visual media that is not time-based.

KF: Speed up control is essential.

MH: Pitch control is also essential so that the speakers voice doesn't become too high-pitched when accelerated.

KF: the chipmunk effect.

MH: If the video controls scaling, playback rate or contrast need the ability to reset to the media defaults.

JA: There are 3 that are related: Navigate multiple media, play/pause/resume, and speed control (that is different from navigation).

MH: Does navigation need to be able to follow markers for search, chapters, or other markers? Example of Google or YouTube annotation.

JA: YouTube or Google is an example of a web-based media players -- do we have to make sure that all players have this as a minimum? Or should the basics be ply/pause/resume and the rest are higher level.

JR: We should call them minimum vs. enhanced the way WCAG does.

MH: We should have change rate of presentation of multimedia.

KF: We should also specify ranges. Are there any industry standards?

<scribe> ACTION: MH to draft proposal for 3.3.a Change Rate of Time Based Media [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action10]

<trackbot> Created ACTION-42 - Draft proposal for 3.3.a Change Rate of Time Based Media [on Markku Hakkinen - due 2008-10-27].

KF: We also need to be able to only download the audio and not the video.

AA: you also need to be able to split out what tracks you want - language, smell whatever.

KF: Is this an accessibility issue or just an access issue?

example of video where the transcript is last -- the sighted user can start watching quickly, but the non-sighted user has to wait until the end of the download to get the transcript.

AA: That is the digital divide, but is it accessibility?

MH: the user agent needs to be able to identify multiple tracks and give the options for the tracks.

KF: It is an accessibility issue, where these videos are high bandwidth and I already have the overhead of running assistsive technology.

<scribe> ACTION: KF to draft a proposal for video section: the option to only download audio and a few use-cases. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action11]

<trackbot> Created ACTION-43 - Draft a proposal for video section: the option to only download audio and a few use-cases. [on Kelly Ford - due 2008-10-27].

<jallan> JR: you have fixed sizes, author size, and full screen.

<jallan> ... user want video twice the size of the screen. how to scroll

<jallan> AA: what if user wants to zoom in on only a portion of the video.

<scribe> ACTION: JR to draft a proposal video section for 3.3.D Text Scaling. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action12]

<trackbot> Created ACTION-44 - Draft a proposal video section for 3.3.D Text Scaling. [on Jan Richards - due 2008-10-27].

JA: brightness and contrast is a legitimate accessibility concern - it is in WCAG

<scribe> ACTION: JA to draft a success criterion for 3.3.E on brightness and contrast. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action13]

<trackbot> Created ACTION-45 - Draft a success criterion for 3.3.E on brightness and contrast. [on Jim Allan - due 2008-10-27].

issue: That we add to the Techniques document: media player controls must be keyboard accessibile and available programmatically

<trackbot> Created ISSUE-15 - That we add to the Techniques document: media player controls must be keyboard accessibile and available programmatically ; please complete additional details at http://www.w3.org/WAI/UA/tracker/issues/15/edit .

<jallan> The audio track may be all or part of the audio portion presentation (e.g., each instrument may have a track, or each stereo channel may have a track) or the audio portion of a video or other media.

<jallan> above is definition of audio track to include video

JA: Do we need need a new section of 3.7 that adds captions as text? Or does 3.7 need to be updated to refer to text captions?

JB: If we don't have an Understanding document, we need to have a rationale.

JA: Then lets mark this as an issue and write a rationale so that 3.7 applies to captions, alternative text and any other text.

<scribe> ACTION: KF to rewrite 3.7 to make it more specifically include text captions. [recorded in http://www.w3.org/2008/10/20-ua-minutes.html#action14]

<trackbot> Created ACTION-46 - Rewrite 3.7 to make it more specifically include text captions. [on Kelly Ford - due 2008-10-27].

discussion of the work load of action items

JB: suggests that written proposals become part of a weekly survey form the way WCAG does it. If no one comments on it, it passes.
... It dramatically increases the work load.

MH: 3.3.F is Time based Media Properties. Where does this fit with other parts of the guidelines.

JR: I don't think this is already in the success criteria.

<Jan> MH: Wondering about WGBH players...with CC in corner...

<Jan> MH: Is that an acceptable way of showiing presence of caption tracks

<Jan> JA: In mdia players, duration and timepoint etc are laready known...

<Jan> JA: Is copyright info etc. req if mainstream users don't?

<Jan> MH: Sometimes that info is rendered in some status area

<Jan> MH: So it needs to be made accessible to ATs

MH: If the progress is a slider control, there needs to be a way to communicate that progress to AT.

JA: If it is embedded, then WCAG says that the information has to be communicated to the user. IF it is a Flash player, then that also has to be exposed to the AT.

<scribe> scribenick: jan

<jeanne> scribenick:jeanne

Alternative Content Stack

JA: to keep with WCAG, it should say time-based media.
... Other than this, did you (Mark H) see anything else that needed to be changed or update?

MH: No.

JA: We don't specifically address other language tracks in 3.3.2. Is this an internationalization issue, or an accessibility issue.

Because we are saying it is available programmatically, I think we are covered for other languages.

Player Behavior

JA: anything that is a option while playing doesn't become unavailable when the video is paused.

Based on Mark's Proposal #4 http://lists.w3.org/Archives/Public/w3c-wai-ua/2008OctDec/att-0023/ua-video.txt
