1.2.3

<jeanne> 1.2.3 Repair Missing Associations:

<jeanne> The user can specify whether or not the user agent should
attempt to predict associations from author-specified presentation
attributes (i.e. position and appearance). (Level AAA)

<jeanne> Intent

<jeanne> Users can use the appearance or position of an item to
determine its importance when scanning a document for information.
Assistive Technologies mostly rely on structured text, such as text
coded as heading or labels. If the browser uses heuristics to identify
text that stands out from others, it can render the page with the best
guess of what the structure could be.

<jeanne> Examples:

<jeanne> Saidah uses a web-based text to speech app to read web pages
when away from her home computer. She tries to find a news article on
a multi-car accident on the freeway she overheard people talking about
on the way to library. She goes to a news website to look for an
article on the event. The website has no headings on the list of
current events articles but has a long list. Saidah does not want

<jeanne> to listen to the teaser for each story, and selects a command
in her browser to figure out the headings from the appearance of the
page. The browser notes the consistent use of a CSS style for phrases
in each paragraph that are bold, in a different color and a larger
font size. The browser then redraws the page with those phrases marked
as headings. Saidah then uses the feature in her text-to-speech

<jeanne> app to read out the headings and quickly finds the article on
the car accident.

<jeanne> Mateus is using a screenreader to complete a form. The form
fields are not labeled so he does not know what should be entered in
each field. He selects an option in his browser to render the page
with structured text, which guesses that the text to the left of each
form field is the label, and re-renders the page with the text
structured as a label. Mateus finishes completing the form.

rrsagent: make minutes
<kford> example 1.6.2

<kford> Randy has a hearing disability where speech at lower pitches
is difficult to hear. He is using an audio browser that reads web
pages back to him. He issues a voice command saying "raise pitch" and
the overall pitch of the synthetic speech is increased.

<kford> Example 1.6.4

<kford> Penny is using a browser that reads web pages to her and
reviewing her most recent banking transactions. She has configured a
setting in the speech configuration for the browser to have currency
spoken as currency instead of digits. She hears a transaction read as
"Deposit, two hundred fifty five dollars," as a result of this change.

<jeanne> ACTION: Jeanne to add IER for 1.2.3 from minutes of 18
August. [recorded in

summary 1.2

The user can request useful alternative content when the author fails
to provide it. For example, showing a filename in place of missing
(1.2.1) or empty (1.2.2) alt text. The user can ask the browser to
predict altertive content if it is missing (1.2.3) or notifiy the user
if the content cannot be rendered (1.2.4).
• Examples of Success Criterion 1.3.2

<Jan1> o Alex has low vision and sometimes has difficulty
distinguishing the fields on web forms. He chooses to have all form
fields displayed with a yellow background and outlined with a thick
black border.
1.8.9 Close Viewport

<Jan1> Gary is a keyboard-only user who is browsing a web page when a
pop-up advertisement suddenly appears in a new window. The
advertisement includes a button labelled “Close”, but Gary is wary of
pressing it since it might be deceptively labelled. Instead he closes
the advertisement with the standard user agent key command for closing
windows and tabs.

<Jan1> Annabelle has multiple browser tabs open and is finished
viewing content in one of them. She activates a close button on the
viewport to close it.

<Jan1> Gary is a keyboard-only user who is browsing a web page when a
pop-up advertisement suddenly appears in a new window. The
advertisement includes a button labelled “Close”, but Gary is wary of
pressing it since it because he knows it might install malware.
Instead he closes the advertisement with the standard user agent key
command for closing windows and tabs.
• Examples of Success Criterion 1.8.10

<Jan1> Robert uses magnification software. After setting up his user
agent, he knows that web content begins predictably one inch from the
top of the window, so he can configure his magnification software to
present content starting at that location.

<Jan1> Courtney has difficulty understanding and using complex user
interfaces. She has worked with her sister to set up her browser to
have only a few of the most common browser controls displayed and she
knows to expect them on every browser window.

<Jan1> Annabelle has multiple browser tabs open and is finished
viewing content in one of them. She activates a close button on that
tab to close it.
1.9

<Greg> Kim and I report that we had moved everything out of 1.9 during
our major reorganization of Keyboard, Focus, and Navigation (on the UA
Wiki), but didn't make clear enough that the section then went away
(in part because numbers changed between when we wrote the wiki page
and when the changes were made). Here's disposition:

<Greg> 1.9.1 User Interface Focus: An active input focus is provided.
(Level A) --> THIS WENT AWAY 2.1.2 requires a keyboard focus for each
viewport, and 1.3.1 requires the cursor be highlighted, so this adds
nothing.

<Greg> 1.9.2 Extensions Focusable: The keyboard focus can navigate
within extensions to the user interface. (Level A) --> NOW 4.2.1

<Greg> 1.9.3 Retrieve Focus: At any time, the user agent can retrieve
input focus from a nested viewport (including nested viewports that
are user agents). (Level A) --> NOW 4.2.2

<Greg> 1.9.4 Return Focus: Embedded user agents must support a
mechanism for returning active input focus to the base user agent.
(Level A) --> NOW 4.2.3

resolved: delete all of GL 1.9 as it is all covered in 4.2

kim and greg will work on IER for 4.2 and incorporate leftover bits from 1.9

<jeanne> ACTION: jeanne to renumber Principle 1 to compensate for the
removal of 1.9 [recorded in
http://www.w3.org/2011/08/18-ua-minutes.html#action04]

<trackbot> Created ACTION-609 - Renumber Principle 1 to compensate for
the removal of 1.9 [on Jeanne F Spellman - due 2011-08-25].
1.1.4 Rendering Alternative (Enhanced): The user can specify the
cascade order in which to render alternative content. (Level AA)

<sharper> Editors' Note: where do we put the ability for the user to
individually pick an image and have the image displayed. It should not
have to be an all or nothing.

<sharper> Added functionality would allow Mary to right click (context
menu) on an image to list and select the rendering of the available
alternatives (thumbnail, original size, full screen, low resolution,
high resolution, alt text, long description, file name)

<sharper> Added functionality would allow Juan to right click (context
menu) on an video to list and select the rendering of the available
alternatives (still image, caption languages, audio languages,
audio-description languages)
1.1.4

<sharper> Examples of Success Criterion 1.1.4:

<sharper> Mary has a learning disability. She finds looking at images
on a webpage very distracting. Mary would like to see all images
rendered in the following order. First, for images with long
descriptions have the long description rendered in place of the image.
If the long description does not exit, she wants the ‘alt text’ to be
rendered. If neither is available, Mary wants the file name rendered.
Added functionality would allow Mary to right click (con

<sharper> menu) on an image to list and select the rendering of the
available alternatives (thumbnail, original size, full screen, low
resolution, high resolution, alt text, long description, file name)

<sharper> Juan is hard of hearing. He wants to always see video on the
page. Also, Juan would like the Spanish language track used if
available, along with Spanish captions as a default. If these are not
available, he wants to see the video with English audio and captions.
If no captions are available Juan wants the the video and English
audio. Added functionality would allow Juan to right click (context
menu) on an video to list and select the rendering of the

<sharper> available alternatives (still image, caption languages,
audio languages, audio-description languages)

<sharper> Related Resources for Success Criterion 1.1.4:

<sharper> Web Content Accessibility Guidelines (WCAG) 2.0; Guideline
1.1 Text Alternatives and Guideline 1.2 Time-based Media
(http://www.w3.org/TR/WCAG20/)

2.3.2 Present Direct Commands in Rendered Content (former 2.1.6):

The user can have any recognized direct commands (e.g. accesskey) in
rendered content be presented with their associated elements. (Level
A)

2.3.3 Direct activation (former 2.7.6)

: The user can move directly to and activate any operable elements in
rendered content. (Level AA)

2.5.1 Discover navigation and activation keystrokes: The user can
discover direct navigation and activation keystrokes both
programmatically and via perceivable labels. (Level A)

<Greg> Per the Wiki page on Keyboard, Focus and Navigation
Restructuring: 2.7.1 Discover navigation and activation keystrokes, is
about direct navigation/activation so becomes 2.3.3 and 2.3.4, which
are now numbered 2.3.2 Present Direct Commands in Rendered Content and
2.3.4 Present Direct Commands in User Interface.

<Greg> Of course, it *was* 2.7.1 but is now 2.5.1, but in either case
should be deleted.

<Greg> To sum up, 2.5.1 Discover navigation and activation keystrokes
has been replaced by 2.3.2 Present Direct Commands in Rendered Content
and 2.3.4 Present Direct Commands in User Interface.

<Greg> It looks like 4.1.6 Properties should include (j) keyboard shortcuts.

<Greg> THEN all of 2.5.1 would be covered by 2.3.2, 2.3.4, and 4.1.6.

<Greg> Thanks for catching that, Jeanne.
Important Elements

<jeanne> From last week's minutes:

<jeanne> 1.10.3 Configure Elements for Hierarchical Views, and 2.5.7
Configure Elements for Structured Navigation?

<jeanne> I think that 1.10.3 Configure Set of Important Elements for
Hierarchical Views is a little long.

<jeanne> So I suggested just taking out "set of important" from each.

<jeanne> <KimPatch> configure important elements for structural
navigation, configured important elements for hierarchical views

<jeanne> <kford> ACTION: JS to update titles for 1.10.3 and 2.5.7 to
remove set of important from title and add elements being configured.
See text from KP. [recorded in
http://www.w3.org/2011/08/11-ua-minutes.html#action01]

sh: complete IER for 1.10.3 and use them as a model for 2.5.7

JS: 1.10.3 is for outline view, and 2.5.7 is for navigation

<sharper> SH 1.10.3 & 2.5.7

<sharper> KP & GL 4.2

<sharper> JS: Document Overall

<sharper> KF - Reconvene at 10 to the hour (:50) time now is 11 minutes past

<sharper> GL: found problem 2.5.1

I'll do summaries

<sharper> wiki page says it should be replaced by something else

<Greg> The group is taking a break until 11:50 AM Pacific Time, in
order to do writing offline.

<sharper> I'm back
4.1.6 Properties

<Jan1> If any of the following properties are supported by the
accessibility platform architecture, make the properties available to
the accessibility platform architecture: (Level A)

<Jan1> a. the bounding dimensions and coordinates of rendered graphical objects

<Jan1> b. font family of text

<Jan1> c. font size of text

<Jan1> d. foreground color of text

<Jan1> e. background color of text.

<Jan1> f. change state/value notifications

<Jan1> g. selection

<Jan1> h. highlighting

<Jan1> i. input device focus

<Jan1> i.j. direct keyboard commands

<Greg> Hopefully the definition of direct keyboard commands will make
it clear to the reader that this includes both hotkeys and accelerator
keys.
Examples of Success Criterion 2.3.2

<Jan1> Fiona uses an audio browser. When the system reads form
controls in the rendered content, it reads the label of the form
followed by the accesskey.

<Jan1> Mary cannot use the mouse or keyboard due to a repetitive
strain injury, instead she uses voice control technology with a
mouse-less browsing plug-in to her browser. The plug-in overlays each
hyperlink in rendered content with a number that can then be used to
directly select it by speaking the command "select link 12". This
prevents Mary from having to say the word 'tab' numerous times to...

<Jan1> ...get to her desired hyperlink.

<Jan1> "select link" and then the number of the link.

<Jan1> (e.g. select link 12")

<Jan1> Fiona uses an audio browser. When the system reads form
controls in the rendered content, it reads the label of the form
followed by the accesskey (e.g., "name alt plus n").

prevents Mary from having to say the word 'tab' numerous times...

<Jan1> ...to get to her desired hyperlink.
Examples of Success Criterion 2.3.4

<Jan1> Vlad is a keyboard-only user who uses a browser on the Mac OS
operating system. When he needs to perform a new operation with the
browser user interface, he searches for it in the menus and notes
whether the menu item has a "⌘” label (e.g. “Copy ⌘C”), which
indicates the direct activation command he can use in the future to
avoid having to traverse the menus.

<Jan1> Amir uses ability switches to control an onscreen keyboard for
the Windows operating system. When he presses the “alt” key the
available browser user interface accesskeys are shown as overlays on
the appropriate user interface controls.

<Jan1> Amir uses ability switches to control an onscreen keyboard for
the Windows operating system. When he presses the “alt” key the
available browser user interface accesskeys are shown as overlays on
the appropriate user interface controls (e.g. "File with 'F' in an
overlay").

<Greg> I'd prefer to also list a more normal example of access keys,
as well as the nonstandard new Office UI, as in "(e.g. File with 'F'
in an overlay in Microsoft Office, or with F underlined in Notepad)",
but I'm not super concerned about it.
summary 1.8

The user agent provides programmatic and visual cues to keep the user
oriented. These include highlighting the viewport (1.8.1), keeping the
focus within the viewport, resizing the viewport (1.8.3), providing
scrollbar(s) that reflect the content size and users point of regard
in a viewport (1.8.4, 1.8.11), and restoring the the focus and point
of regard when the user returns to a previously view

ed page. Additionally, the user can specify that all view ports have
the same user interface elements (1.8.10), if and how new viewports
open (1.8.6), and whether the new window automatically gets focus
(1.8.7). The user can close any open window or tab (1.8.9).

<Greg> This is for Guideline 1.8 - Help users to use viewports and
orient within viewports.

<Greg> Programmatic is covered in Guideline 4.1 - Facilitate
programmatic access to assistive technology

<Greg> Something like "providing scrollbar(s) that identify when
content is outside the visible region (1.8.4) and which portion is
visible (1.8.11)"

<KimPatch> stepping away for a minute

1.10

The user can view the source of content (1.10.1), or an "outline" view
(1.10.2), and may specify the elements to be used for the outline view
(1.10.3).

<Greg> For Guideline 1.10 - Provide alternative views

topic summary 1.11 Guideline 1.11 - Provide element information.

The user agent provides information about content relationships (e.g.
form labels, table headers)(1.11.1), and extended link information
(e.g. title, internal vs. external) (1.11.2)
Summary 1.11

<Greg> If we change "provides information" to "presents information"
it would be clearer that it's about presenting to the user instead of
providing programmatically.

The user agent presents information about content relationships (e.g.
form labels, table headers)(1.11.1), and extended link information
(e.g. title, internal vs. external) (1.11.2)
2.5.7 Configure Set of Important Elements: The user has the option to
configure the set of important elements for structured navigation,
including by element type (e.g. headers, list items, images). (Level
AAA)
2.5.7

<sharper> Intent of Success Criterion 2.5.7 :

<sharper> Often the user agent will choose by default the elements it
considers important for structured navigation, however these may not
be relevant in all circumstances. It may be that the user wishes to
navigate via informal mechanisms such as microformats, decentralised
extended elements, or via a particular styling which is used to convey
a structure in the visual navigation, but which does not exist in the
element hierarchy.

<sharper> Examples of Success Criterion 2.5.7 :

<sharper> Fred is blind and wishes to navigate through the menu
structure using the Tab key, however the menu is a set of nested list
elements with a particular HTML class attribute denoting the
menu-submenu relationship. Because Fred's user agent allows him to
configure important elements he can explicitly include the class name
as an important element for navigation.

<sharper> Jane uses a mobile device (and is often situationally
impaired) and often encounters tables laid out using floating DIV
elements with specific class names denoting the visual styling. In
this case Jane cannot use the cursor keys to move around these tabular
layouts having instead to use the tab key to move sequentially
left-to-right top-to-bottom. Jane's browser does not provide the
facility for the configuration of important elements and so she can
not pick

<sharper> the classes associated with these DIV element, and therefore
cannot use the cursor key used to move logically through columns or
rows.

<sharper> Related Resources for Success Criterion 2.5.7 :

<sharper> None

<sharper> Jane's browser allows her to configure important elements
and so she can pick out the classes associated with these DIV element,
and therefore use the cursor key to move logically through columns or
rows.

<Greg> I'd like to add something specific to the Fred example, but
what would it be? That is, how would it work in practice? "He then
assigns a keyboard shortcut to navigate to the next element with the
same class name as the element that has the focus"?

<Greg> I also note that this example goes beyond what is actually
required by the SC (which is not necessarily bad, but it may mean the
SC needs to be broadened if we want to include this functionality.
Specifically, the example is about using attributes to select
"important elements", but the SC only discusses elements types (e.g.
h1, li, img).

jeanne: we have made examples go beyond the SC. and have language in
the document about this so folks are encouraged to do more

sh: reviews 2.5.3, and it talks about underlying semantics, also 2.5.1, 2. 3.

<Greg> How about adding: "Rachel uses a command to navigate to the
nearest parent header above the current focus location. However, she's
using a document that uses a class other than h2, so she adds this
class to the browser's definition of what it treats as a header."

last sentence for fred: He then assigns a keyboard shortcut to
navigate to the next element with the same class name as the element
that has the focus

<sharper> Fred is blind and wishes to navigate through the menu
structure using the Tab key, however the menu is a set of nested list
elements with a particular HTML class attribute denoting the
menu-submenu relationship. Because Fred's user agent allows him to
configure important elements he can explicitly include the class name
as an important element for navigation. He then assigns a keyboard
shortcut to navigate to the next element with the same class name as
the

<sharper> element that has the focus.

<Greg> "Rachel uses a command to navigate to the nearest parent header
above the current focus location. However, she's using a document that
uses a P with a specific class rather than h2, so she adds this class
to the browser's definition of what it treats as a header."
1.10.3 Configure Set of Important Elements: The user can configure the
set of important elements for the hierarchical view, including by
element type (e.g. headers). (Level AAA)

<sharper> Intent of Success Criterion 1.10.3:

<sharper> Sometimes authors will visually convey relationships between
elements by spatially grouping them, by giving them the same
coloration or background, and so forth. Users may not be able to
perceive those attributes, such as when using a screen reader, or when
strong magnification makes it difficult to make a mental model of the
screen layout. In those cases the user agent can assist by providing a
view of the data that groups elements that that user agent

<sharper> perceives as implying relationships.

<sharper> Examples of Success Criterion 1.10.3:

<sharper> Jane uses a mobile device (and is often situationally
impaired) and often encounters tables laid out using floating DIV
elements with specific class names denoting the visual styling. In
this case Jane cannot use the cursor keys to move around these tabular
layouts having instead to use the tab key to move sequentially
left-to-right top-to-bottom. Jane's browser allows her to configure
important elements and so she can pick out the classes associated with
thes

<sharper> element, and therefore use the cursor key to move logically
through columns or rows.

<Greg> Jan notes this is looks like the wrong intent paragraph.

<Greg> a///

JR: perhaps the intent would go in 1.2.3

kf: need to consolidate 1.10.3 and 2.5.7

<Greg> Discussion of whether we should have two separate SC for
configuring elements for structural navigation vs. structural views.

kf: AT provides structural navigation (and Opera)

<Greg> Greg notes that few browsers support structural navigation
commands, but Kelly notes that assistive technology supports it.

JA: suggest merging

issue: make a resolution for 1.10.3 and 2.5.7 (merge/separate).

<trackbot> Created ISSUE-88 - Make a resolution for 1.10.3 and 2.5.7
(merge/separate). ; please complete additional details at

<KimPatch> 4.2.2 (former 1.9.6, before that 3.11.6) Retrieve Focus
[moved, unchanged]

<KimPatch> At any time, the user is able to retrieve input focus from
a nested viewport (including a nested viewport that is a user agent).
(Level A)
4.2.2 Retrieve Focus

<KimPatch> Intent of Success Criterion 4.2.2 (former 1.9.6, before that 3.11.6):

<KimPatch> Historically keyboard users have had difficulty with nested
user agents trapping keyboard focus, preventing the user from
activating host browser commands including navigation and menus.

<KimPatch> Examples of Success Criterion 4.2.2 (former 1.9.6, before
that 3.11.6):

<KimPatch> Ari is using a video hosting site where each page hosts a
nested media player. He presses Tab until the focus in on the media
player, then presses Enter to activate and put the keyboard focus on
it. When he’s finished watching the video, he presses Tab to navigate
to the comments below the video, but cannot get the focus to leave the
video player. He presses Alt+Left to return to the...

<KimPatch> ...previous page, but that also fails because the video
player is consuming those keystrokes. Luckily, Ari knows that
Shift+Esc will return focus from a nested user agent, with or without
its cooperation. Thus, even a badly behaved nested user agent cannot
prevent Ari from getting on with his work.

<Greg> The SC previously had mixed singular and plural, so we fixed that.

<Greg> The current draft guidelines include the wrong text for 4.2.2
(a copy of the text from 4.2.1); this text is the version we'd
submitted via the wiki, corrected for singular/plural.
